I don't doubt it at all. If you know your class/what you're doing, you can pull off some mad shit in this game.
I could solo arms/cath with my rogue @ 48. arms/cath with my Warrior @ 49. GY/Library/Arms on my pally @ 37 (skipping houndmaster boss). Many elite quests on my warlock that other classes couldn't while still red/orange. Killed 17 dustwallow marsh murlocs in 1 pull on my mage @ lvl 40. Soloed the rare spawn elite in mara on my rogue @ 48 & my hunter @ 46 for his phat 49 bracket lewt.
There's just a few things off the top of my head. Rather than calling bs read up on this stuff to find ways to do it yourself.
