We just started our first outland instance (we = my 4 shamans + the fifth shaman played by my wife who joined me in the adventure)...
the whole group died at leat 3 times, and some chars only 3 or 4 times ... we took down the two first bosses .. but no way to kill down Nazan .. it's master was easy, but the fire aoe kill us all on every try ...
that's harder with multiboxed chars .... can't say if we can take him down ... it's really hard ...

btw ... go pick-up 30 zepplin stuff on the ground .. 30 x 5 ... this is PAIN !!!!
