this if it's been fixed and he is just bad
Just as a note - a guildy of mine (83 ret pally) was unable to complete this quest as of last night. He was dpsing and healing his butt off but couldn't keep Cenarius from dropping. I jumped in to try and help but I was phased, so he tried the tactic of cursing and skipping the quest for now. It seemed to work.
I'm not saying it's for sure still broken, acheter wow gold but he doesn't strike me as not competent enough to finish this quest - it was pretty easy on each of the three toons I did it on.
I'll feel really stupid having posted this if it's been fixed and he is just bad.
