Now, I’m not saying either Hank or Caira are OP. I think both of them are quite balanced(Caira could use a slight heal nerf but that’s it) when not together, but this combo makes every monster’s head hurt.
You attack Caira -> Hank shields.
You attack Hank -> Caira heals + Hank goes invisible.
You attack anyone else -> shield + heals.
I think the real problem is that Caira’s heals are way too strong for AoE. She has pretty much the same healing speed as Val, but she can heal all hunters at the same time if they’re close enough + herself.
I don’t know about others, but I never have a problem with, for example, Val/Hank combo, and I’m pretty sure that’s because you can switch targets easier and force Val to focus some heals on trapper/assault because of ability splash damage. Caira has no need for this as her grenades will heal up any splash damage instantly. Also, Val actually has to recharge her medgun while Caira can spam it without a break.
I think Hank is just fine as he is, but Caira could use a slight nerf, either to her healing speed, heal grenade reload or heal grenade radius. I’m not really sure how else this could be fixed other than slightly nerfing Caira’s healing speed.
