Boxing, and Mana.

So.. i'm relatively new to the boxing scene with RAF being the lure that brought me to it. My first group was 2 locks and a paladin.
It worked like a charm!
Now i've gotten my elemental shammies (3) to lvl 30 and i've realized i'm drinking a lot from their mana falling like rocks.
This wasn't a problem on my warlocks due to having great mana flow (life tap and life drain) but it's really bugging me at how slow i'm progressing through STV (grindheaven)

Anyone have suggestions or their own methods of keeping the mana pool up? or do i have to drink after every pull >.<

If you are having mana issues, the best thing to do is to drop a mana spring totem, then pull mobs to the totem. Dont cast lightning shield and stay away from shocks, they tend to eat mana like no other until later levels.

I had mana issues as well at those levels. Always have Mana Spring down, don't shock, and don't waste mana on lightning shield. When you hit 50, get your shaman quest and hit sunken temple for your Ancient Mana Spring totem, which will help a lot, though the true mana-problem-killer is Water Shield. That's a ways ahead for you though.
