Ahahaha well, that's not really an issue with Gon2 itself, but the nature of trick room teams I guess. Try using Gon2 as a lure for fighting types I guess? Dusclops is slower than alot (all?) of them and has the bulk to take any payback in that scenario, he'll enjoy Pain Splitting Rohpushin's base 105 HP too if he really needs to, otherwise, Recover with Gon2, switch to Dusknoir, TR... Idunno, I'm not that great with Trick Room haha.
@Ech0ez: Golbat's real selling point is how easy it is for him to switch in, Fighting, Grass, Bug, Ground, you name it, it's a joke to Golbat.
