>>51692562I think the only things I'm really worried about are:
A.) How hard of a STAB boost you get (I've seen people say 3x if you already had the typing when that's stronger than STAB Adaptability if I'm not mistaken? Sounds too much but idk)
B.) Whether or not Terastalizing takes priority. If it takes priority like Z-Moves or Dynamax, I think it could end up being seriously annoying, kind of like in the context shown off in the trailer with Tyranitar winning a check matchup against Gallade by just turning into a Ghost type. Doesn't seem too fun to have your momentum completely trashed by something as unpredictable that's also predictable at the same time; it's essentially just Sucker Punch and King's Shield's issue. If it was based on speed, not really a big issue; Tyranitar would be forced to run Choice Scarf to handle checks like Gallade if that was truly its biggest concern, and therefore not as unga bunga.
C.) They NEED to just bring back Hidden Power with the new Tera moves' effect, or make these new moves a permanent addition whether Terastalize remains or not. This is the best way to handle Hidden Power's long-standing problem with IVs, and I'm really not happy that they made the solution a gimmick move that is highly likely to be removed along with its gimmick in the next generation
D.) The hats are okay I think, but I wouldn't be sad if they removed them or changed them in some way. I like the gemstone concept though, I'm a sucker for pretty gems.
