I'd like to spec my 5x druids resto and lol at ppl trying to kill me. It would probably get old quick though since I wouldn't really be able to kill them either.

5x mages with the right setup in AV would probably be able to make a blizzard gauntlet through some of the choke points that people might not be able to make it through. It might take more than 5 mages to make an impenetrable blizzard wall but it's something im looking forward to trying.
