So, apparently it was only just a tooltip error that hellfire didn't generate as much fury as harvest life (
discussion here). I specced harvest for wind lord because the aoe profile used it if available, xD. (obviously I'll spec harvest for H wind lord, so I have an aoe filler once the boss is into wind bomb range.)
But anyway, I found it misleading for the aoe profile to use harvest life if specced. Was that an oversight, or was the thinking that if you specced harvest life, then it's because you wanted to use it?
