Nah, sinister is way more useful than magneto in story. I’ve just ran through act 6-9 and exploring act 8 and he’s doing most paths and bosses. It’s mental how much he can take on. A r4 will take fights in act 8 in like 15 hits or less which lets you bypass abilities and nodes especially with the extended stun you just wait out unstoppable/evade/falter etc which wrecking them with degen. He’s honestly so broken for story I can’t believe they are giving him out to everyone via tickets, a duped 6 star basically gets a cav to valiant if they can parry.
