So I'd like to say the holy at 240 was Good considering the stun time was like nothing and it's really not fair.
We as WHM need these last resort spells, plus taking away our Thunder and giving us blizzard isn't really fair, considering we normally use DOT's over a stone 1,2, move.
I think IF we needed the 200 potency instead of 240 at least give us 10 or 15 secs of stun then reduce by 5 until immune or something.
