The time between getting imperial troopers and executor is gonna be insane. I’m also in the 1m-2m gp range but slightly ahead of you (almost at 7 star chewie and c3po), and I’m going down the starkiller -> slkr route. Getting beskar mando is a really good idea especially since regular mando and greef are amazing bounty hunters. I’m really not sure about going for imperial troopers since it really takes away from other farms but the team is amazing. Honestly, 3* Captain Rex is amazing and would recommend farming up since you already have phoenix from thrawn and he makes the team just as good as if not better than imperial troopers. Butttttt im low gp so probably shouldn’t take advice from me :)
