How viable is darth vader (for PVP). My current team is 5* Lumi,Sid, 4* Luke,Dooku,3*chewie
also have phasma and 4* talia . I would like to replace chewie and Luke with phasma+vader or phasma+kylo. Since he can only be 4* is he viable in the end game? So 7* kylo or 4* vader? what if I can even remove dooku for vader and use phasma+kylo+vader?
