Hi, so im not having a problem with that part of the quest, its just when i get to the final stage, i get him to 1 health and he just doesnt die, so i thought i would wait a bit and nothing, i cant even click on the guy. i tried logging off and on again, deleting and reaccepting the quest but nothing is working, this is a bug and i need to do the quest for draenor pathfinder so its really pissing me off
Same thing is happening for me. I know there is supposed to be a point where you get help to take him down but once I’m stunned, he just continues on his rampage and throws me around like a rag doll then eventually phases out and goes back to his starting place. I, too, have gone through this and dropped and restarted, disabled Add-Ons etc. I’m not sure what the issue is.
EDIT: OK! So I finally was able to finish the quest. Yesterday, I could not complete stage 7 or 7 so I just left it unfinished (I DID NOT abandon it) and went back to garrison for the night. Today, I want to Wor’var and disabled all of my add-ons at the location. Then I rode to the Gates of Grommashar and the quest had reset. I went through the quest again (this time with no add-ons) and there was no issues. I hope this helps.
