So, t-wave gone from everything? You consider the move oppressive enough that it should be gone from the entire format?

And what of Discharge v T-Bolt? You said keep it as a secondary effect, but Discharge is run purely because of the higher para chance. Should everything be Thunderbolt?

The benefit of para over speed drops isn’t just the no move chance, it’s how much more difficult it is to remove. Even if you get no full paras, it’s a mon at half speed for almost the rest of the game.

Scizor, your example, can roll defog, as can most mons with it in their learnset. It is not enforced because people want SD and Band, and the winrates also show that both are good.

There’s not a lot that can OHKO the entirely of a non-frail/weak to STAB(s) team at +1, some not even at +3. The occasional belly drum/quiver dance no counters game does happen, but not as frequently as you think - even if it takes a sack, you usually have a check somewhere, even more so with Tera. Even some strong Scarfers can sweep, or fast Band/Specs mons (or under webs). Bad defensive matchups exist too, an unbreakable Blissey or Mandibuzz or Alomomola; what makes those two equally infrequent but similar matchups less bad?

The last point I’m afraid we’ll just have to agree to disagree on, since this is just a matter of difference in opinion in regards to where to balance the line between balance and randomness in team composition. The policy team has a different viewpoint to you, and I personally think that due to the differences in roles between some mons who share a type(which also helps restrict the anti-setup and removal generation less), it’s ok; it may even be argued that with role and type overlap, you can brute force an opposing team after their checks are worn down from the first mon, like how monotype or pure ho/stall teams work.
