Secondary resources are a lot more interesting to play with, and it might just be time to scrap non-healer mana altogether. While it's true that you could turn mana into a utility resource for dispels and the like, you could also do that with cooldowns - if you're worried about PvP you can just put the relevant abilities on shared CD with charges, allowing you X uses of any utility ability within a given time. Heck that might even make PvP more interesting in terms of choices you make.
