Yeah.. wearing Infused Ancient Rathound armor on Hard was already underwhelming before this nerf, its resistances were strong but not very strong and the bonuses (+heat and +cold resists) were kinda underwhelming. I wished I had made a Regenerative Vest as usual.
This was the armor I had after looking at lots of leathers and super steel fibers.
It wasn't all that amazing in DC on Hard, especially in long fights, damage would get through easily and I would miss having something else going on like the healing effect of a Regenerative Vest quite a bit.
One solution to this contention would be to allow the unnerfed higher qualities on Hard and above, would that be reasonable?
