JTR healing???

ok, so i'm confused. maybe i just overlooked it and it's simple or maybe it's not. In GAC i can beat Rey with my SK, heck now i can even do it in TW thanks to Juhani's omni. However if JTR is on the team i can only win on GAC simply because SK healing immunity can't be dispelled. but otherwise every time anyone hits JTR she takes no damage. she just heals. can someone explain this to me? is it something i easily overlooked. i am stumped. thanks in advance.
