Lol, I got bored one week and made a warrior just to kill them. For 52, he's badass. More hps dps than any 60 warrior I know. Of course, I had the ability to practically hand pick every item he's got, including the pet proc weapons.
Just an FYI, you can lvl up to get the higher level passive AAs, chain die a lot to get to 52, go kill him, and if you desire, go back and get a bunch of rez's. It's kind of stupid and a waste of time, but it does work.
I will say, get you an instant click item for the AE debuff. I did the entire seru signet earring quest for my instant clicky, but my mains are a bit more powerful than most folks.
Hope it helps.
And btw, yes, you can absolutely shroud down to 50 and go fight them.
