I'm healing almost every day in raids, and i'm sick of player OOM always, So ill tell you my trick.
- Get lot of +healing bonus.
- Cast Rank 1 heals. (Light of heal, lesser heals, anything)
You will notice that you receive lot of bonus from +healing on your rank 1. Every 1,5sec, I can heal for 1400-1500 for the cost of 30mana.
So now, no reason for you to be OOM
