might and might not be helpful, but hey here we go
backround info:
in AQ20, the 2nd boss, General Rajaxx, is a scripted event by blizzard for you to go through like 10 or so waves of mobs to get to the general, you get help from 5 npcs and at the end of the event, the more npcs alive the more rep you get, and Andorov (one of the NPC's) will sell you epic plans and pots and junk, anyway..
Need a hunter:
Use eyes of the beast with a cat that has prowl, use your pet to walk upto the boss, hit him, remove you eye of the beast buff, and the general will run straight at you, ignoring all mobs.
done, rajaxx without having to clear the mobs
the only problem is: you still need to kill the mobs
from what i remember when you start the script by talking the the NPC he will aid you for the first wave of mobs, then after the first raid he will act as though the event is over, giving you your rep and allowing you to buy items from him, leaving you to deal with the remaining packs by yourself.
whether or not you want to do it this way is upto you, keeping in mind the NPC's are alot of dps so if you bug it you wont have their dps, but hey, its upto you
enjoy
