When I play my SCH, its my "healers choice tree"

Is my HP critical?
Is Tanks HP Critical?
Does tank have any debuffs(or am I paralyzed?)?
Is DPS HP Critical?
Do I have any debuffs?
Does DPS have any debuffs?

Of course, this various in situations where I know the debuffs are more deadly then usual, but in most cases, particularly 4 man content, a dead healer is a wipe, anything else can be fixed.
