Hrmm... whatcha gonna do when he pulls everyone to the center and you have to run away?  Suddenly you aren't in melee range anymore and can't interrupt the spells (until after the arcane explosion when you can move back in).  So he would get you with his random fireballs/arcane missils/frost bolts during that time.

Then you have the water elementals to deal with... and you would all need to be careful to scoot around to avoid the blizzard - melee does get hit with that as well.  Still, with pots/bandages and very good gear I suppose it might be possible....  It would make a great U-tube video, lol, simply because it would be extraordinarily difficult. 

i think it would be posible interupt everything i can say that much lol when arcane explosion all stay and clos when elementals 5 rogues go and kill em think it is very posible
