I think nerfing Last Wills is the obvious option. First, make moves follow their normal rules. Laxpras is stating the obvious, but it needs to be said. No more launching Rocks or Mementos when you're under Taunt. Certainly you shouldn't get your move if you're asleep. If that leads to Explosion spam, then option 2 can also be enacted, if that's to 1 or 2 or however many we feel is the limit to a balanced metagame.
Leaving it in its current state is pretty clearly not an option, yes.

Not to be snide, but if the metagame becomes shitty with Explosion spam but it's kept because it's "part of the metagame's character" then people won't want to play and the metagame will die a very quick death. It's happened before.I gotta echo the sentiment of slowing the sawsbuck down on calling for nerfs and bans. Maybe Explosions are a part of the metagame's character.
Also, folls, this is definitely the time to consider accuracy-lowering moves. Accuracy *does* apply to Last Will moves. Yes, Smogon hates accuracy stuff with a burning passion, but if you've played any DnD, you'll know exactly how useful it is to be able to go from having to roll a 20 to just having to roll high on a d4 twice in a row.
I'm having good luck adding Mud Slap or Flash to a pokemon with Protect or Substitute and some passive damage.
