Oh noes! Change! (Warning: nerdrage)

So, while killing time today, I came across a post on the test realm forums for WoW's next big patch.  In the new build, every class is getting some work, and some specific specializations are seeing huge changes...I'm staying away from those posts to avoid the weeping and gnashing of teeth from the parts of the community that don't follow development and therefore don't know that this stuff has been discussed for months already.

One of the more general changes being made is a mana cap across caster classes.  At the current level cap, you're looking at X amount, and it'll eventually cap at Y when the level cap rises in the next expansion.  Simple concept, right?
