What a complete lack of perspective. More people probably engage in world PvP than arenas. Those people would argue that world PvP should have priority, not arenas — and they'd actually have higher numbers to back themselves up.
As developers, it's Blizzard's job to balance competing interests. They can't pander to an extreme minority of the game.
Anyway, the developers said they're looking into a way to make world PvP more balanced to make up for these changes.
For the record, my priority would also be on arenas if I played Mists of Pandaria. I'm just aware that there are multiple sides on this issue.
