It is quite hard to see what they want to do with mistweavers. Pretty much every patch has changed the healing style of them. Granted a few of the patches did contain needed nerfs but this one seems to be way over the top.
This patch seems to have removed any ability to AoE heal. I know we were looking good for tank / single target healing but I've not been able to play since the last two patches where they have reduced Soothing Mists by a lot and now increased Surging Mists mana cost in this patch.
I think it would be good to hear from blizzard now on which direction they are wanting to go with monks. If they have decided that they will primarily play as melee and heal by dps'ing I may rethink my decision to reroll in MoP.
