That really isn't a fair comparison as it would be nearly impossible to coordinate ranged frost traps to keep 4-5 of the mobs sheeped while you blew up one at a time. The only reason the all-mage group worked was because there was only one mob attacking at a time, and that one was slowed greatly and only got off a few hits before falling over dead.

Unless we're talking about some other videos besides the ICC/BH trash farm videos.
