Ok, this is my first informative thing that I(me) recently discovered, in the past almost 2 years, i didnt really notice this. IF this is old news and posted countless times, just ignore me.
So yeah, the goblin mech room. If your standing in the middle of the track that is pointing toward the rest of the zone(toward vc) you can cause whatever mobs are on you to continulously run back and forth trying to get you.
All you do is strafe right(or left too) so that your not on the track, mobs turn around running toward the end of the track, and back down toward you once they reach it.
Now just strafe back onto the track wher eyou were when the mobs are close and theyll run back down the track and back to get to you. You can just ping pong them forever.
SS upon request, easy to confirm tho, its deadmines. that is all
