As the title, I feel my mutant class 7* is lacking. Is taking onslaught to R3 worth it even with a max sig 6*? Will I notice the difference or am I better off with storm, sunspot or bishop? I never use him but I said the same about silk and pig and now they’re my go to for everything.
I do ok in BG and as an alliance we’re plat4/5


Help a fella out if you can.
