Four games are left in the NA LCS regular season, and we have four teams separating themselves from the pack: TSM, CLG, C9 and the surging Team Impulse.

From there, we have three teams tied in the middle of the pack for the final two playoff spots: Team 8, Gravity and Team Liquid. Behind those three, you have the stragglers Dignitas and Winterfox holding onto a sliver of hope that a miracle could occur.

Then you have Team Coast at 1-12, needing to win four games in a row and for Winterfox to lose all four of theirs to avoid auto-relegation. History is staring Coast in the face, but not the good kind; at a winning percentage of 7%, Team Coast are possibly headed to the record books for the worst season in European or North American LCS history.

Changing Fates

Professional eSport rosters are not stable. You can have a team sign one day, not live up to standards for two weeks, and then dropped the very next week to sign the new shiny player in the amateur scene. When your jobs are on the line and falling out of the LCS can change your life drastically, teams and management can't always give the new guy the allotted time needed to mesh with his new team.

Outside of visa issues that messed up the first weeks of the season, four teams have had constant roster changes this season: Team Liquid, Dignitas, Winterfox and Team Coast. Let's take a look on how their changes have affected their season with only four games to go.

Team Liquid

The biggest storyline possibly of the entire season has been the question: Keep Keith or Keep Piglet? Keith's record was much better than Piglet's with the team, but on paper the former world champion outclassed the high school amateur-turned-pro in every way. Liquid had a good environment for the week and went with Piglet for Week 7, even following Keith's 2-0 performance the week before.

The week didn't turn out too hot for Liquid. Piglet played some of his best games on the season, but Dominate and Quas had possibly their worst. TL went 0-2, falling into a tie with three other teams and in danger of missing the playoffs if they can't put it together the final two weeks.

Verdict: Piglet is a good player. Dominate is a good player. Quas is a good player. Piglet played well this week and Dominate along with Quas did not. But unfortunately for Piglet, Liquid have shown they can be a strong team with Keith. For whatever reason Quas, Dominate and even Fenix to a lesser extent play better with Keith on the team.

No, that doesn't mean Dominate or Quas hate Piglet or vice versa. Sometimes in sports teammates simply play better around a different player, no matter the skill level or how well they play. Piglet is a really nice piece, but you can't continually try to force said piece into a puzzle when Keith has fit in like a glove and done his job superbly.

Liquid with Keith are 6-2. Liquid with Piglet are 1-5. It isn't entirely Piglet's fault for that record, but Liquid can't afford to miss the playoffs. Yes, if they work through this and Piglet benefits in Summer from sticking with him, then it could work out great, but do they have that luxury?

Winterfox

A lot of Winterfox's changes were due to visa issues, but they made a big change this weekend by moving Altec to support, sitting Imagine on the bench and putting their head coach Paragon into the starting AD carry role.

They got off to a hot start against TSM in their first game together, grabbing two kills with a clever level one strategy, but couldn't hold onto the lead and lost in the mid and late-game. The second game didn't have much to be happy about either, Winterfox getting steamrolled by a Gravity team that, while having an up-and-down season, have stuck with their starters throughout.

Verdict: There are a lot of factors to WFX's roster switches. Altec apparently wanted to go to support and take pressure off his shoulders, so Paragon was the obvious choice. Altec played well in his first two games as a support, looking strong in lane as Leona but still having some issues when it came to the later game and team fights. Paragon also did well in lane but fell off when the pressure was applied, face checking bushes and dying needlessly in key moments.

Winterfox are now 5-9 and have a small chance at the playoffs. The position on the roster that should have most likely been changed was Avalon, their starting top-laner who has struggled all season, but he was kept on and delivered another low-impact round of play.

I would say Winterfox should go back to their old lineup with Altec as their ADC and Imagine or Gleeb as the support, but roster decisions are never as easy as they look on paper.

Dignitas

It has been all about the jungle with Dignitas. Long-standing member Crumbzz left the team after the first games of the season, CloudNguyen played for six games, and then he got benched for Azingy following a win in his last game as a starter. Dignitas were able to pick up a win against the hapless Coast to start the weekend, but got shut down against Cloud 9 to drop to 5-9.

Verdict: All three junglers have a KDA at 2 or below this season, but it's still a mystery why Cloud was benched after a game where he won. Azingy came in and had the worst first two games imaginable, messing up his runes in the first game and then having another blowout in the second. He played much better his second week, but Dig are still only 1-3 with him and all but certain for one of the two relegation round spots.

Cloud played a much more aggressive game than the other two Diginitas junglers, dying more on average but making a lot more plays for Shiphtur and CoreJJ to take advantage of. Azingy only has 14 assists through his first games, and Cloud finished his time as a starter with 51. In six games.

Maybe Cloud had personal problems with the team and that's why he was moved out so suddenly, but the statistics show that Cloud was probably the right choice between the three junglers they used.

Team Coast

Team Coast lost a lot of games in a row, traded in Jesiz for Mancloud hoping he could conjure up the magic he had in 2013, and Team Coast learned that magic is not real.

Verdict: Unlike the other teams in this list, Team Coast were in a position where they had nothing to lose when they made their roster swap. Coast got destroyed by CLG to close out the weekend, and we've now gotten to the point where watching the games have become sad.

They went for a Hail Mary to save their season, it has failed miserably; they now need Santa Claus and the Easter Bunny to bring them the greatest eSports miracle of all time to avoid relegation.

Around the Horn

In the only game to not involve one of the four teams rapidly changing their mask from week to week, TSM beat Team 8 to lock in their first place seeding going into the IEM World Championship break next week. Team 8 got knocked down to the three-way tie for the final two playoff spots with Liquid and Gravity at 7-7.

Lustboy celebrated by raising his shoes in celebration, mirroring T8 Maplestreet's ceremony from the week prior. It was a pretty good celebration.

It was funny. I laughed. And we're done with LCS for the next two weeks.
