Just wanted to future-cast it now, since it won't be popular.
There is a good chance PvP weapons/armor are gonna have some special stat that pertains to attacking Knights (or something of that nature). Basically the resilience type phenomena on WoW--but for weapons and armor.
Why? Because then people will have to craft all new PvP gear 2-5*. New recipes will have to be bought and so on. Basically, we will get to pay for our equipment all over again.
I hope i'm wrong...but i'd at the very least be prepared if it is the case. I.e. prepared to not be shocked.
Okay Harold Camping.
You keep predicting stuff.
