What is the downside to DeathTrooper (DT)?

Don't have him, but if I were to make a guess I would say because then you'd have to replace another character, if you're not going to have krenic lead then you will likely have palps, with palps comes Vader, TFP definitely in there also. then either shore trooper as he is empire Or baze because at this point you could just throw him anywhere and he'd be amazing. After this you only have one free spot that isn't pretty much mandatorily given away, and that is most likely going to boba
