My guild started heroic modes this week I found it almost impossible to keep up in mana on heroic feng. we had to get spriest mana cds just to last though the fight. The only real break we had in healing was Spirit of the Fist
that was because we either shielded the epicenters or stunned them the rest of the fight the raid dmg was fairly high.
i guess my question is how to deal with this i have taken to stacking spirit just so i can feel like i can last thoughout the fight i have been using spirit flask/food. i have logs of the kill and wanted to know if there are any thoughts on what to do here. or am i just miss using my mana.
