I don't see a point in sticking with Mana when we do not use it whatsoever. Yeah your mana drops, but it is never an issue where you might go oom that it used to be. Mana is pointless.
I am not ignoring PvP, it is just not the main focus at the moment. My points are not moot from the get go just because PvP is not the main focus, as I did state that I put thought into PvP for the spec to make sure it wasn't crazy. If you can find any PvP problems, point them out. Also Fire needs some sort of change because right now the spec has had a horrible track record. I don't want to go through another expansion of nerfs every patch just because of how it scales, and I am sure many players who main a Mage feel the same. The class is archaic overall and really needs a fixer upper.
