Siddown's post has already been answered by Peng and just to add a little bit more food for thought. PvE weapons are goung to be ilevel 530 (+8) at the very least coming 5.3 seeing as how it will cost only 500 PvE points to upgrade them. Anyone aquiring an ilevel 522 weapon is able to aquire a thunderforged version of it sooner or later giving it an even bigger advantage.
And while not many groups will get to kill Lei-Shen or Ra-den for that matter many on my server already have 3-4 HC's at the very least on farm. This means these people WILL aquire the heroic weapons and upgrade them fairly soon. You don't have to clear ToT to aquire much of the heroic/heroic thunderforged gear.
Because it does not favor the actual PvP community in any kind of way. It's throwing the PvE people some candy hoping to turn PvP into another side game for them to increase their interest while doing nothing for actual PvP players aside from cheapening their game. And again, if that would be true it should be just as easy for PvP people to join into PvE, it isn't. Try getting into an ToT Raid with your 493 ilevel PvP gear.Doing the vice versa only makes sense and should have happened a while ago; and not only to make it easier for PvE'ers to get into PvP but to get ALL players to have an easier time to get into PvP. Why you folks continue to stick to this archaic notion of "I MUST WORK FOR EVERYTHING EVEN IN A GAME AND EVEN IF MOST OTHERS DON'T LIKE IT" I'll never understand. I'm just content knowing Blizzard is no longer catering to your whims; and yes, they were catering to your whims as was shown in Cataclysm with the heroics.
On topic, and the next hit goes to resilience and PvP power gems. Pretty much halving their effectiveness. Please tell me how this is a positive thing PvP players and does not help PvE players who're not using these gems anyway?
