Top level PvP gear will be at a disadvantage to top level PvE gear, and PvE'rs literally all run past eachother so they can get their quests dont quicker.
Looks like world PvP is done.
Also, if they normalize gear is certain PvP locations, things will get even more ridiculous. It's Blizzard pretty much saying "you must world PvP here". Some of the best world PvP encounters I've had have been out in the world. I was levelling my mining once in Burning Steppes, and came across a pally who was doing the same. We kept fighting that spanned over two zones, he called a few of his friends, I called a few of mine. It was a fight that lasted like 2 hours.
He was a super geared PvE pally and I was a mediocre geared PvP player. If this encounter were to happen in 5.3, I'd have no chance at killing him and he'd wreck me.
Mod edit: There's no need for flaming.
