Currently I don't really feel like playing anything rated PvP wise at all as there's simply no point to it. There is no new gear for me to obtain, I've got the T2 of last season and every piece is 391 so all I gain is two phenomenal ilevels with the new gear till 5.3. I've got pretty much every RBG achievment aside from 300 victories and HotH.
Well there's still 3's, just that it doesn't offer any desirable rewards either and I currently lack a decent frostmage for that. So all I'm left with is sitting there looking at rated PvP and ask myself "Why bother"?
The only enjoyable PvP left to me right now is random battlegrounds, as sad as that is. It's easy fun on the side without the risk of "losing" anything or being forced to search for hours upon hours for a decent RBG group with high enough ratings.
PvE people get new achievments, new transmog stuff, new pets, mounts and other vanity stuff thrown at them alongside new vastly superior gear. What exactly do we get? What is our incentive to actually go through all of the effort of finding decent Arena/RBG partners when there is simply no reward whatsoever for doing so? Fun alone simply isn't going to cut it, especially not when random battlegrounds are more accessible, easier, faster and without the risk of actually losing any rating?
