100 hp idea and armor scaling idea
Maybe armor at each ql should have 10ql armor value but it should stay QL*(armor hp)
For simple Exaple 33 ql armor (15/15 armor and 33*50hit points) etc.
If it could be still problem soo maybe in PVP only destroyed armor (red one) should all the time give protection. But while pve this protection would be disabled
When anyway scaling str/con still gives strong characters the advantage of time spent in game.
