Not everyone plays this game to raid. I know, I know … radical statement.
And I am so sick and tired of every single guide that I read INSISTS that you must get hit-capped above else. And for a mage, being hit-capped means reaching an astonishing 17% hit … even with talents that help along the way, this is a ridiculous amount of hit from gear and gems. Just ridiculous. Especially if you are not intending on raiding … for heroics you need so much less! No one seems to write blog posts for how to be uber in just heroics … so you get the mistaken impression that you have to get five zillion hit points just to do well in those 5 mans.
In fact, for Heroic five mans, the hit cap for the heroic bosses is 6%. Which means you hardly have to get ANY hit points from gear or gems if you choose talent points wisely.
Wow!! That means you can free up those yucky hit-gem spaces with lovely juicy spell power and crit gems (or haste if you’re arcane) … and you can blast away at those mobs to your heart’s content. You’ll zip up those dps meters because of the extra damage you’re now doing … not wasting it on hit points that you didn’t need anyway.
