With the rework, vader got alot speedier especially against rebel teams. The rework was meant to even out the CLS meta in arena. Ok, I see you actually have the potential to build a fairly strong sith/empire squad etc. EP, vader, maul, tfp. Don't underestimate tfp. He is the fastest toon in the game and he does pretty decent dmg esp with all the debuffs. And his ship is really good as well. Probably gotta work on your Nihilus to 7 stars as he is quite a game changer. The other issue would probably be your mods. You needa get better mods. Its a long farm I know but you will get there.
