Destruction's Depths

Hi, I could use some advice on completing this quest. The first few parts are rather easy. But when you get to the Norn group and there's a massive amount of destroyers that spawn. Is there anyway to take them down without having to wipe over and over? I've tried bringing SH nukers and Winter, but the destroyers just cut through my eles like butter. The character I'm running is a monk, so I can't influence tanking or damage of the destroyers that well.

So can anyone help me? Just use wards and your good. That's pretty much how I stayed alive vs them.
