This is a video that FiestaFan did a while ago, with only 8 people and we completed the KQ...
you'll see (through the blurs) how we pulled groups of mobs.. and with the crazy wheckless mages AOEing everything... and the fighters starts to run off and get the new gorup when the mobs are almost dead...
the group needs to move very fast, i think the hardest thing is to coorperate... the fighters needs trust the clerics and not be afraid to tank..
it's more ideal if you have at least 2 fighters who could devestate... we tried doing it with just 1 fighter and the desvestates and mock doesnt last long enough and DDers tend to draw all the aggros... which didnt end up too well..
(the picture of ralath still makes me laugh LOL)
