Quite possibly. I do certainly hit harder with fewer combats. It doesn't make much of a difference to me since I don't usually string adventuring days anyway.
I have to admit that abundant natural healing also doesn't impact my games too heavily. I use my own lasting injury rules (converted from what I used in 4e), I don't pull punches when it comes to traps (humanoids often smear poison or feces on their spike traps, prompting saves vs poison or disease), I often have intelligent monsters plana ahead and improvise in dangerous ways, and I'm not afraid to focus fire a PC if it feels like the monsters would recognize her as a threat that needs to be put down fast.
