Why would I reroll because I don't know who some random PVPer Rogue is?
Why would I care about any PvE'r that isn't in a top 3 world guild of multiple raid tiers (equiv to what r1 9 times is if not still significantly harder, but just humoring the PvE folk.)?
For me personally though, I don't. I believe pve is as big of a joke as PvP balance over the years. In PvE it's just who exploits first and gets it taken away or who class stacks the hardest using multiple raid groups for gear for a fight like spine ( pvp has it's own flaws too with que dodging/wintrading/ddos attacks etc ). I'll give props to the vanilla raiders etc and people that downed m'uru pre nerf though.
This game pretty much lives on the social aspect in how the saying goes "For the weak minded you don't quit wow, wow quits you." I could quit if I wanted to, but it'd take the people I play with to stop playing for me to truly find it not fun anymore.
