I am actually really surprised they made this announcement today without also including the new cosmetic rewards they have planned for the PvP community. Near the beginning of Mists of Pandaria, I believe it was Cory Stockton, who mentioned their goal was to introduce more cosmetic rewards and a larger variety of them at some point in the future for the pvp community.
They did make a blue post just this morning about cosmetic items saying they're still working on "motivating" the PvP'ers to play more.
And I just feel the need to quote Nakatoir here because I just love him.
"I have to ask; why is it that you feel entitled to have better gear than someone of lesser skill and as such bridge that gap between you both even further, giving you an even more distinct advantage?
If players are able to fight with an equal footing in regards to gear, then you will be able to tell who has more skill as the better player will obviously be able to attain more rating. This change should excite you with having a better chance to show your stuff and surpass 2.2K rating, push yourself beyond your known limits and try for the best you can!"
This is the mindset they currently have and I just love it. It's just perfect.
