Im just getting into 5-man Heroics and im having mana issues when it comes to taking severe raid damage as Discipline. It seems like if the whole party gets under 50% health I have a hard time getting them back up to full health without going oom. This is an alt so I have a lot to learn but im not completely unschooled in the spec. The main healing spells im using are Power Word: Shield, Penance and Greater Heal. Any advice?
