I feel like this type of fighter needs custom AI that prevents them from tagging out at low HP.
The same goes for Dead of Winter and Immoral Fiber too for example.
This type of fighter that relies on getting to low HP or outright dying to be most effective are much too easily cheesed by letting them tag out so you can simply kill them last to circumvent their abilities.
I'd be much more bothered by Dead of Winter reviving if i had to actually kill her first (or bring a tagout move with me), because right now she's just kind of tanky but otherwise useless imo.
