I’ve got 8 at 72 or above, I believe.
Maya: Thoughtlock build is OP8
Axton: Standard Double Up/Gemini build is OP8
Sal: Standard “lol raid boss” build is OP8
Zer0: Melee build is OP8, gun build is OP7
Gaige: Death-Trap build is OP8, Anarchy build is OP4
Krieg: Bloodlust/Mania build is OP8
I’ve got a bunch of characters somewhere near the end of TVHM or early UVHM (Scorn Maya, Nuke Axton, Brawn Sal, Bloodlust/Hellborn Krieg) and a bunch of allegiance runs in NVHM (Dahla Dahla Bill, the Commando, is the only one near the end though).
