After the group wipes they continue to stay around the island pulling everything they can onto the group and pulling Onndasta on spawn to cause a reset.
Zalond also runs alot of old content pugs during the week Firlands/25 uld/25H icc etc.
Whenever you get to a boss with very rare loot I.e. Rag H LK and Yogg zero he will quietly swap to master looter just as the boss is about to die with what seems to be the intention to ninja loot the mount. (If you look his name up on Thurissian there are a few thread about him being a ninja)
So please be aware these guys are trolling around the server trying to ruin your day and avoid pugging with them...it wont end well.
P.s. Whoever carried Zalond to his Challenge mode gear i am very impressed because i have seen him booted out of pugs for not being able to out DPS the tanks.
