After you kill General Nazgrim and go down the elevator you find a room which is filled with a bunch of trashmobs along with a demolisher in the middle. If you've been there you know which room I am talking about by now.
From there you're able to see the platform of Malkorok so I figured I'd stealth past all trash and go up there ALONE. Once I was there asked my raid to wipe so I could use my mass ress from up there and it worked just fine! The raid has to make sure to move into the room quite a bit tho, so you're close to the boss platform, otherwise u'll be out of range.
Can save you some time if you have the boss on farm status! You wouldn't wanna wipe and risk having the mass ress debuff.
I can imagine people have been doing this before, not hard to figure out, however I was unable to find another post about this specific trash, other than using the demolisher to kill some of the trash pulled from the next room.
If this happen to be a repost please point it out so that it can be removedVery minor expoloit, if you even wish to call it that. (maybe wrong forum?)
