Saw some posts comparing Tera to Team Preview, and honestly I thought they made a lot of sense. However, saying that Tera should be fine because we went 4 generations without Team Preview and had to deal with a similar amount of guesswork is imo pretty silly. There has only been maybe one mon ever that was broken by not having access to Team Preview, and it literally came into existence in the same generation Team Preview was added. Meanwhile, Tera could potentially be balanced once players gain experience with it, however, there are still many Pokemon that would need to be banned entirely because of Terastalizing, because even if you know what’s coming, they’re simply a nightmare to deal with and overall very uncompetitive, which imo warrants looking at Tera very differently than one would look at no Team Preview.
Also idk why a separate Tera ladder is getting so little traction with council. Whenever I played Gen 8 randbats I would always play on the no Dynamax ladder, and I’m sure I’m not alone. Tera fans seem very very invested in this mechanic, so I’m not sure why the assumption is being made that this ladder would die. I got behind the OM idea in the past but honestly reinstating a banned mechanic doesn’t seem very OM-like, so I think it’d make more sense to just have it be its own thing (a la NatDex).
