I searched for this and found nothing similar
In the Fleshwerks in Icecrown there is some mobs with around 2-3k hp that can be killed for the 15 scourge quest in the Argent Tournament. Those mobs are zoned, and vanishes when you complete a quest chain in the fleshwerks. Tried this on my friend's char on his comp, so got no screenies (sorry).
Myself is done witht he chain, so can't use it myself![]()
Hope this might help someone that think dailies take too long, or die when pulling too many mobs. Fleshwerks is also very close to Icecrown Citadel, and you can easily reach it by flying from doing the Battle before the citadel dailies.
