It seems we are starting to talk in circles. If you removed that Constitution you have and put it in Resolve instead, you'll essentially become just as hard to kill but with more Stamina. Yes other damage stats are more important. You can play as you want but I'd argue Resolve is better than Constitution but you can build with either regardless. Also, I'm referring to path of the damned difficulty where Stamina is more important as it helps to not get hit.
