>>55768769>Of course, this data would be somewhat skewed by what pokemon are doing the tera-ingThat's going to heavily skew what Tera types get used. Bug is a strong pivot type since it resists Grass, Ground, and Fighting while having uncommon weaknesses (with its only major weakness being patched up by HDB). You're not going to terastallize your pivot, you're going to terastallize your sweeper. If you're going for a defensive tera, it will almost always be Steel, Water, Fairy, or Poison since they're the best defensive types in the game.
Using VGC stats will also heavily bias your metric since Bug can't leverage its decent defensive profile in Doubles. Your Bug isn't going to be able to absorb an Earthquake or a Close Combat for the rest of the team, but being able to cover most of Steel's weaknesses is Bug's greatest niche.
