your demons mana pool

look demons dont have much for faster mana regen and i dont know what stats go in to it but for demon locks they can get mana feed i think and that gives your demon mana when you drain mana or life tap.

my current spec

http://talent.mmo-champion.com/?warlock=235002203102351025051033115100000000000000000000000000052003005000000000000000000&glyph=100320020406&version=9889

so you just rolled a lock.

warlocks are great for new people and as they level they are complex to the naked eye and i want to say they arent but in the end this is a game of numbers and a warlock with a pet is 2 against one mob you are on the winning side so far but thats not enough to just have numbers you need to know how to play.
