Yeah I know they cannot lure behind pillars all time but there is just nothing can do for one-shot. And yes, I'm using Force Armor always when big cast is coming
I don't play Republic much, but, if it has a cast, can't it be interrupted?
Is it like...(damn, forgot the name) the boss droid with the flags(or whatever they are) when if he finishes the cast and all the flags are same color it's a one hit kill?
Or is there no such mechanic? Just heal and pray?
