How much longer is it going to take for there to be a regenerator clause? Surely if baton pass is "too complicated" or "too good" or whatever, that they have to flat-out remove it from regular competitive play, they realise that switching between two bulky regenerator pokemon like toxapex and say, tangrowth, is under the right circumstances, a way to stall like 200 turns to win?

What needs to happen? A pokemon that resists everything Toxapex is scared of, that has similar bulk and also regenerator, for it to stop? It will probably happen eventually, but it should be sooner than later.
