I usually run heroics, but since somewhere in 3.2, i have started to get really low on mana from time to time. i generally just do heroics, but i have also noticed this on somewhat old content (OS10, naxx10, VoA10). since i rarely run high content (ToC and ICC), i really have problems with this, especially in heroics like VH, CoS and those others where there is a decent time between pulls.
anyone who can give me some hints on how to stop this paladin from ooming?
