It's been literally a day since Crawdaunt, Hawlucha, Kyurem, Lucario, and Venomoth have been banned. As said in the tiering thread , possible suspects for quick bans will be looked at each week during RU's Beta stage and voted on by the council. While your statements have truth to them, as the Pokemon you mentioned are indeed quite powerful and have a large impact on the current metagame, the whole purpose of this tiering method is to make sure certain threats are worth banning before actually voting on them out of the tier, hence the weekly quick ban phase.As for a specific response to your statements, I do agree that Feraligatr has been pushed out of the shadows and into the spotlight thanks to the banning of its main competition, Crawdaunt. While Feraligatr was never bad per se, Crawdaunt not only had dual STAB over it but also hit relatively harder thanks to higher Base Power STAB moves and access to Adaptability. Now that Crawaunt is gone, it can truly shine. Dragon Dance and Swords Dance sets are both viable, with the former terrorizing offense teams and the latter easily wallbreaking with its sheer power after a single boost. I'm personally a bigger fan of the Dragon Dance set since it is harder to revenge kill without a Pokemon that has a Choice Scarf and it boasts superior coverage since SD Gatr will most likely run Aqua Jet.The remaining Pokemon that you mentioned I don't really see as banworthy at the moment, simply because they are all rather easy to play around, especially once you know their set. Necrozma is extremely susceptible to Taunt, as are most variants of Cresselia, and while the former possesses a good Special Attack stat, it lacks coverage moves beyond Hidden Power, making its offensive prowess limited prior to setting up. Cresselia is extremely bulky but really lacks any sort of offensive presence and can oftentimes be used as setup bait.Heracross has quite a few hard checks and counters, including but not limited to: Gligar, Cofagrigus, Doublade, Nidoqueen, Jellicent, Qwilfish, etc. While Heracross can carry coverage moves to hit some of these Pokemon, it requires prediction and / or the loss of a more important coverage move. Heracross is also relatively slow, so it is easily revenge killed by a host of Pokemon barring Choice Scarf variants. I won't deny that it is a strong Pokemon in the RU tier, but I hardly think it's worthy of a ban at the moment.Cloyster is an interesting Pokemon, mostly because it has the capability to play two very different roles on a team. Most notably it has access to Toxic Spikes and Spikes as well as Rapid Spin, making it a great utility addition to a team, or it can go the offensive route with Shell Smash and attempt to sweep. The reason why I don't think it's worth looking at for a quick ban is similar to my reasoning above. It can be hard stopped by a few Pokemon, and it becomes susceptible to priority after it has weakened its defenses with Shell Smash. Its average offenses mean that it sometimes won't even be able to OHKO bulky Pokemon like Milotic and Slowbro after a Shell Smash boost, and is easily revenge killed in return. Its utility set is rather mediocre as it is weak to Stealth Rock itself, meaning that its ability to come in and remove entry hazards is quite limited. Its abysmal Special Defense also leaves it KOed or heavily weakened by most neutral special attacks.Shaymin has always been a good Pokemon, but suffered similarly to Feraligatr, as it was mostly outclassed by Celebi prior to it departing the tier. Now that Celebi has gone, Shaymin has become really useful. Seed Flare is really hard to switch into especially if the 40% chance to lower Special Defense by two stages occurs, and Shaymin's access to Synthesis and a host of good coverage moves like Psychic for Poison- and Fighting-types, Dazzling Gleam for Dragon-types, and Earth Power for Steel-types makes it difficult to deal with outside of dedicated special walls like Florges. I'm not entirely sure if this warrants a look into for a quick ban, but it is certainly one of the most useful and powerful picks on offense and balance teams at the moment.Overall I'm really enjoying the current metagame with the recent quick bans, as it really frees up teambuilding, as you won't need a check to Specs Kyurem, or a switch-in to Crawdaunt (those hardly exist to begin with). I've been playing around with a lot of different things such as webs offense and other Quiver Dancer users. I can't say for sure what might be next on the chopping block, but I can say that the current metagame is a lot better off than it was before.
