We know many monster attacks deal a portion of "'normal' damage even in T3
Some people believe the game is becoming too easy.
The problem is normal defense will go from really important to uselless.
My solution: normal damage should protect against every damage type, but with 1/3 of effectiveness compared to specialized armor.
This is not a suggestion yet, this is a question to all players. (and it'll get more attention here anyways :p)
It'd definitely make having an Anciet Plate set seem more viable...
