We had the raidquest to kill the frostgiant and you all know a has an ability that jumps everyone close to him (aprox 30-40m close to him) into the air. But if you tank him at the peak in the north, right next of the gunship encounter which is east afaik of that part of icc, you can stand at the railing and avoid being jumped into the air.
Tank him here in the north:
Stand here at the edge (works on every part of the place):
No fall damage and more time to dps him.
