Countering Nihilus led Dooku squads?

I'm also a droid user F2P lvl 79 and I get to beat them when I don't get fucked with RNG like 86 ALWAYS picking JE to assist with his special or when HK-47 doesn't land any debuffs after his special (I'm always around top 100, can't get more than that because of the same reason). My attack order is 47-88-86 and I use boba, I managed to unlock R2-D2 which I'm already gearing up since stealth doesn't trigger counter attacks and the burning will help out a lot along with the stuns on his basic, I'm hoping with this I can solve my dooku problem and climb at least till top 50 like I used to be before nihilus appeared. In the meantime I'm gearing up my siths too cause when my shard starts to get the zetas and stuff droids will be useless anyway until a rework for GG or something. So yeah, if you didn't get R2-D2 gear up a new team, like rebels with wedge+biggs or a sith team or an empire team with the troopers which are awesome now (shoretrooper a pain in the ass to get for us still tho)
