While the mana regen is not that great compared to before I am pulling maybe 3-5 different packs of trash before I really need to drink, I went to do H UP but got owned by Second boss and Gauntlet run is kicking my butt but I have not read to much about it, I dont think that it has changed a whole lot, but I did replace a couple of MP5 pieces with some Crit/SP pieces so that might be my issue, I brought water now too so I dont have to worry about it much. But I have not had an issue on regen after every trash pull I can probably clear to the first boss in UP before I have to drink. I do have a priest for my healer that wands so she never really runs out of mana since I am always using JoW on the mobs.

My Macro /Castrandom [target=party1-targer] FS, LvB, CL, LB on all 3 shaman, one of them just made 80 and her gear is kind of gimpy compared to the others but she does ok, she is the only one I truly have issues with mana.
