I'm surprised, amidst all the Tera controversy, there hasn't been much talk about banning Tera Blast as a middle ground.
I think a lot of the frustration from mons like Volc abusing the mechanic come from Tera Blast augmenting your coverage in ways that were never intended. Volc's been kept in check in past gens by things like Ttar or Heatran because it was never meant to have Ground coverage. removing TB from the equation still allows for strong defensive Teras, but you can't use it to surprise your opponent with a coverage move of literally any type.
and it doesn't remove creativity - ChainChomp could still Tera Fire to boost Fire Blast, for example, but a smart player will already be scouting for that move if they need to. removing TB just means you couldn't get utterly surprised by a move God never intended that mon to have.
(disclaimer: I'm a fan of Tera - just throwing this out for conversation.)
