I don't even know if we lose to anyone. Hardest mu is wowo which I'm not sure I'd classify as 4-6. Jump back 2 does so much work against manta it's insane, he's also free on oki which is where catwoman can just f him up. Arrow does well but to give him the advantage over catwoman while he loses in footsies and up close and catwoman has j2, cat dash and amazing walkspeed to punish bad arrows and reloads is a bit of a stretch imo. WoWo is the closest for being able to deal with all of cw's bs and for controlling neutral well which is where catwoman usually wins her matches.
