Hello all,

I currently run a level 80 empire team with Krennic Lead, Deathtrooper , shoretrooper , magma trooper and royal guard. Recently, I am starting to think that the team may need a change, in particular with royal guard, although his stunts and buffs and high turn meter gains are also good . This team applies a ton of debuffs so I am considering Vader for an insane saner throw. However, despite my high level I am still not the best at this game and struggle to maintain my top 1000 arena rank. Any advice given will be appreciated on possible character changes.
