I like pierce percentages. I always imagine if someone gets hit for 1000 armor damage that it has to have an effect on the poor underlying vitality. You just got half your armor ripped off by a 2 handed axe - I'm pretty sure that's going to leave a mark even if some of your armor is still on you. It also leaves room for higher piercing from weapons like daggers/bows etc.
HOWEVER IF I GET A VOTE IN ALL THIS - My group of friends really liked the armor system in DOS2 much better than DOS1. I think the people that are complaining are the vocal minority. The armor system allows us to have stronger CC and statuses. If you let everything pass through or make ONE armor type then the entire game balance would need to be different. If DOS 3 has this exact system of armor we'll still be very happy.
