For bugging a boss like illidian is easy!
You need:
.The tank need good ranged dps. Mage, warlock, shaman elemental and priest are the best.
.The tank only use ranged
.Tank never lose the agro
How you bug the boss:
.Go to the boss and after boss focused you(tank), you(tank) need move two litle movements to backward and after to right or left side(move a litle not much)
.If the boss not atack you(tank), don´t move more!
.You(tank) start doing ranged damage.
.You(tank) need get more agro than other people of your party, for it, told im to stop some times, for you(tank) not lose agro
The boss are a diferent move script's and can´t move in all directions, you only need get 1 good position and boss can´t atack you.
