The more we discuss this, the more it feels like Tera team preview is going to be our best bet of keeping it as a mechanic. We have to remember we’re trying to balance both Tera and the early meta as a whole, which has been stated repeatedly yet it hasn’t seemingly sunk in for some viewpoints. I don’t care to discuss how oppressive Gholdengo and Chi-Yu are in the current state as it pertains to Tera’s balance, cuz even in a non-Tera meta those two are still major threats; it does not further this convo.
What I would like to know is if I can devise some counterplay to Chi-Yu if I know beforehand which Tera it isn’t. If it’s Dark, I’ll plan my Chi-Yu response accordingly…instead of also needing to plan for the possibility of it being Tera Fire or Tera Grass in addition to its item and coverage simultaneously—and then do that for the five other mons I’m facing. If we’re going to combat Tera’s unpredictability, we do so by gaining information.
The early pro-Tera statement that the meta will develop and the common Tera types will rise to the top seems to have been correct: we are not weighing the possibility of 6-7 different types on each mon, it’s actually more like 1-3, and the types are specific to each mon. It’s worth bringing up Annihilape, a mon that was screaming through the tier before Rage Fist’s mechanics were correctly implemented on Showdown, is actually cooling off on the radar of the list of banworthy presences according to the surveys—and this is, again, with Tera fully available. I don’t mind playing passively around Annihilape as I wait for my opening, but it’d sure be nice to not have to guess right on Tera Water or Fairy to eliminate it when that chance arises, or else I lose a mon or more. Actually, the guesswork associated with each threat on that survey is majorly tied to each threat’s ability to dodge reasonable counterplay with the proper Tera.
I don’t think micromanaging STAB or non-STAB Tera should be entertained; we still want to foster creativity as the meta further changes and we lose that if we intentionally strangle it here and now. I don’t mind some of the other suggestions tho: trading an item slot for Tera/only one Tera per team, etc
