We'll see if Tactician mode can be tough enough to make losing armor basically fatal no matter what. I don't think that's a good direction (in fact, I'd like to see losing armor a little less dangerous). I would not be surprised if Skin Graft gets nerfed. It is probably the most versatile skill in the game. We shall see if other factors make it less powerful though.
Yeah, I'm not a fan of armor being such a dominant factor in combat either.
But, aside from Skin Graft's armor loss, if fights are longer then an ability that only gets used once per fight has a lot less kick than it does in short fights.
