you forget ONE major point.
If gear was normalized in BG´s and or arena, there would be absoluteley no excuse anymore for loosing to someone besides facing the counter class.
Right now lots of bad playing can be hidden behind the "but he got at least 300 more resilence and pvp power than me"-argument.
Well yeah we still got DC`s, lag spikes, server lag, "dunno why you dead, the heal just finished and die anyway", cat ran over keyboard amd such.
Aside from that, if people werent forced to do BG´s to get gear there would be much less BG´s played, which equals a way higher waiting time for those that still want to.
But on the other hand if there was no grinding needed in pvp, there would be no benefit in grinding pvp, which again would kinda kill bots in bg´s damn you, now i am really undecided...
