Suggestion for my sith team

Hello, I'm playing sith team and I'm rank 1 at my payout for more than two weeks everyday. I just wanna take tips from more experienced sith player.

I play dn lead, sith assassin, savage, shoretrooper ( I won't have sith trooper or gk for LONG time so no need to mention it) and my 5th is where I'm not sure. I have ep 5* and dooku. I'm able to achieve rank 1 with both but ep seems way to paper.. He literary get kill from some not hard hitting aoe. So what's your advice? And if you have spare time you can give advice on my mods. Its really hard to find someone to talk about siths as everyone on my shard play just two gays baze chirru. Here is my profile https://swgoh.gg/u/collapse/

Thanks for any constructive reply
