http://forums.worldofwarcraft.com/threa ... 7690&sid=1This post from the bug forums might explain the lower dps and the sever lack of mana rather quickly that I know a few of you who are still survival mentioned.
If you dont want to click the link the gist of it is that Explosive shot is not proccing any on proc abilities therefore your mana regen etc is not working as well as any trinks. The forum belief is that it was screwed up when they tried to fix the extra shots of ES from proccing JoW procs. Hope this helps some of the survival hunters, I know we have many of them.
