London Spitfire are doing extremely well in the Overwatch League at the moment. They've won all four of their matches, and are keeping pace with both New York Excelsior and Seoul Dynasty, while creating a gap to the rest of the pack.

However, after their performances in week two, it could be said that NYXL and Dynasty are ahead of them in the Power Rankings.

Spitfire lost a couple of rounds to Dallas Fuel and Los Angeles Valiant, and it just so happens they were on the same map: Oasis.

Oasis is a Control map in Overwatch, and it's seeing a lot of play in the League in Stage 1

London Spitfire are sitting on four wins and zero losses right now, joint top of the League

In week one, Spitfire beat Florida Mayhem 3-1, but it could've very easily gone to a tiebreaker if Oasis had gone a little differently.

Mayhem reached 99% in both rounds, and Spitfire were incredibly close to letting the win slip through their fingers.

Right now in the Overwatch League we don't have any map bans, so Spitfire are probably nervous whenever Oasis appears in the Control map section.

They've been totally fine on Ilios and Lijiang Tower, so what is it about Oasis that's bamboozling the Korean squad?

Mail Esports' Matt Porter has watched their games on the dreaded map in close detail to find out.

Wasted ults

Fury played D.Va a lot against teams on Oasis, but was rarely able to make an impact with his Self-Destruct.

Some of this was down to bad luck, as we'll touch on later on, but a lot of it was down to poor positioning. He'll need to get some tips from Fusion's Poko.

There was a Winston Primal Rage from Gesture against Fuel on City Center which did nothing, and although Profit did pull off an amazing Junkrat ult against Valiant, there was a bizarre moment against Fuel where he exploded it with no enemies in sight.

London Spitfire are having some troubles on Oasis, having lost twice against Fuel and Valiant

There was also the wild west showdown between two McCrees, which Birdring lost, and a couple of Lucio ults which didn't save the team for very long. Which brings us onto the next point.

Poor timing

Everyone's seen Profit's amazing Junkrat RIP-tire on City Center by now, where he went on a merry jaunt across the rooftops before dropping in behind Valiant and picking off three members, including the two supports, simultaneously.

It was a highlight reel play, but in reality, it barely changed the outlook of the round.

Valiant were on their way to the point from spawn, and before had engaged, they had lost three members. So, they simply retreated back to spawn, and everyone gained a little more ult charge along the way.

When they came back for the next attack, they hadn't used up any resources, and Profit was down one RIP-tire. All it cost Valiant was a little time.

Plus, Spitfire charged out to meet them, and ended up over extending and losing the fight.

Another couple of instances of poor timing occurred in the first round against Valiant on Gardens.

The fights on this map are always extended, and Nus blew his first Mercy ult a little too early. Valiant were able to fight through it, and when Unkoe used his ult, he was much more effectively able to get crucial resurrects when the real fight began.

Nus was unfortunate again soon after when he used Rez to get back Fury in mini D.Va form, who was killed instantly before he could re-mech.

Outplayed in mirror match-ups

In the first round of their match against Los Angeles Valiant, both of the teams went with the same set up: Lucio, Mercy, Winston, D.Va, Pharah, Tracer.

In this mirror match, where tactics and pure skill were the only differentiators, Valiant came out on top.

Mostly, this was down to Agilities' Pharah play. He managed to get direct hits on Rascal's Pharah on multiple occasions, forcing Nus to focus his Mercy healing on his primary DPS.

While Nus was tied to his Pharah, Valiant's Unkoe on Mercy was free to heal the rest of his team. The healing output from Bdosin on Lucio just wasn't enough, and Valiant were able to pick Spitfire apart.

All in all, the support play from opposing teams was often better on Oasis. Dallas were able to flip points without using Valkyrie or Transcendence, while Valiant used those same abilities to much greater effect.

Spitfire's troubles on Oasis are down to a number of factors, including poor timing on ults

At the start of their four tank plus Moira team composition battle against Valiant on University, Bdosin got picked off early. While he was respawning, Unkoe had already charged his Coalescence.

In the next fight, Unkoe used his well, and while Bdosin was able to charge his to 100%, he got picked off yet again before he was able to use it. Meanwhile, Unkoe was already back up to 55% charge on a second ult.

Hero choice / reluctance to swap

Lucio's a good choice on Gardens, but when Spitfire were continually unable to take the point after Valiant grabbed it early, Spitfire were banging their heads against a brick wall.

Lucio can get you into the point quickly, but he lacks the damage of another support like Zenyatta, and if he gets split up from the team, he also lacks any long range healing abilities.

Spitfire went with the four tank approach on University against Valiant, and although it worked for a time, Soon quickly switched over to a tank killing Reaper. Adapting to that could've made the difference.

The London Spitfire have an incredibly talented roster, and will continue to win games anyway

In fairness, in their match against Fuel on Gardens, Spitfire did do a lot of swapping, but only because they started with a fairly odd combination of heroes.

They went with a Reinhardt going in, and against an opposing Junkrat, his shield was gone in seconds and he was the first to die.

Spitfire were also without a Mercy for over half of the map, and while Fuel were getting off key resurrections, the healing from Ana and Lucio wasn't enough.

Spitfire did eventually swap the Lucio for a Mercy, but it was too late. At one point, Spitfire had three ultimates to Fuel's zero, but when Profit got caught out and went down just before a big fight, Valkyrie wasn't ready yet to bring him back easily.

Big plays from opposing teams

During the game and in the post-game analysis we saw a lot of praise given to Agilities again for his big play on Roadhog towards the end of the University round.

Fury and Rascal had Self-Destruct and Graviton Surge available respectively, and those two combined should've been enough to allow Spitfire to hold out for the win.

However, a great hook from Agilities sent Rascal's Zarya down the hole in the center of the point. It takes a long time for a low mobility hero to get out of there, and Valiant managed to mop up Spitfire in that time.

Going deeper into the season, it will be dangerous for them to have a bad map in Oasis

It's also worth mentioning that a bit of luck that went Valiant's way though. Rascal fired his ult into the floor, and did catch five members of the opposing team in it.

It's hard to see in the replay, but you can just about see Fury start to charge into the Graviton Surge and activate Self-Destruct. However, Envy had just launched his into the corner, and the blast knocked Fury's clear of the group, and behind the Reinhardt shield.

It's tough to know whether Spitfire's bomb would've been effective if Fury had placed it exactly where he wanted it, but if it had, we'd be looking at a 1-1 score.

Spitfire will likely be working hard this week to prepare better for Oasis against other teams

So, as we head into week three and the very real possibility of more Oasis, will Spitfire have fixed their problems on the map?

Having a bogey map as we head later into the season will be very dangerous, especially when they start coming up against their direct rivals at the top of the standings.
