Hey there hunterfolks!
Yesterday our guild started and spent the entire evening wiping on General Vezax. It took us a couple of tries to get the fight right (and as usual, our second try [40%] was our best try up until the 15th), but when we were finally going steady we hit enrage at 5%. After loads of disappointed shouting in vent, we took a look at your DPS meters to see what could be done. Three DPS were underperforming; a priest who is undergeared for Ulduar but which we're carrying through, a warrior tank which off-specs arms in most of his tanking gear on bosses that only need a tank, and, to our surprise, a hunter kitted out in full Naxx 25-man gear - she was pulling off between 1700 and 1800 DPS.
So we had a little talk with the hunter and it turns out she was using aspect of the viper for the entire fight. Somebody told her to use aspect of the hawk and only switch to viper when she ran OOM, which she attempted the next try, but her DPS stayed roughly the same. She fiddled with aspects some more and eventually logged with the message that it was something she couldn't help.
Seeing as we're currently more or less hunterless in the guild, what I basically want to ask the people here is: were we right to speak up to the hunter for dealing ~1800 DPS on Vezax? Is mana regeneration indeed a serious problem for hunters on Vezax? Or is she simply being a huntard not following any rotation?
If it helps, here is her armory; http://eu.wowarmory.com/character-sheet.xml?r=Moonglade&n=Elex%C3%ADa
