Never seen a healing class this bad in any bracket, Played about 50 games and wated to gouge out my eye balls. If any priest has even the slightest clue of how to play he is going to roll you with next to no effort. Do yourself a favor and play 3s or another healer.
If you want to play a healer paladin, better go with necro prot pally with magistrate lego. Watch some twitch vods Drainerx has. But you are very limited in set ups (need fury warrior mostly with imp victory).
