After banning Palafin, Iron Bundle, and Shed Tail/Cyclizer, I would like to see a pause on quick bans. Instead of focusing in on Chien-Pao and Roaring Moon next, there should be a deep dive on this generation's gimmick. I personally dont think splitting into two separate OU tiers is viable, so that leaves either making it more transparent or banning it altogether. I want to say I completely disagree that revealing Tera Types at team preview is anything like a complex ban. Im of the same opinion as all those who already said it earlier in the thread that its not modding the cartridge since it could be done in real life with pen and paper. But if even with the team preview reveal, its judged to still be broken, we should ban Terastalizing altogether then. l really think its going too far trying to take away same type Adaptability or defensive typing from Terastallzing, since now youre altering the game mechanic itself. I do wish Game Freak would have done something themselves. With that said, I think this generation's gimmick should be given a chance of being balanced at least before getting banned.
Those are my thoughts on the direction OU should go. I have nothing to say about the meta itself.
