Shouldn't we all pump the breaks on calling a class good or trash until after hitting max level? Of course SCH is gonna feel the most incomplete after the last patch since so many skills were taken out, but we haven't had a chance to fool around with the lv80 toolkit yet. Not to mention that a majority of players are higher than the average item level for the lv71 dungeon, making it seem even easier than normal. You may get a better grasp of the difficulty for healing in SHB once you reach the lv75 dungeon.
