I realized recently that I have a pretty weak 6 and 7 star mutant class. I'm probably going to rank up Mr. Sinister soon, but I was wondering if I should rank up Bishop too. I leveled him up after his buff and thought he was kinda underwhelming. I recently came back to the game and recognize that he's now regarded as one of the better mutants. So what should I do and is there something I might be missing about him that I didn't see in initial testing. The rotation I used was building up prowess with parries, throwing an sp2, and repeat.
