Can warriors server as a dps member of a group?

[Nordenwatch]

I was in a group once when I was in my 40's where the warrior stayed at 30% HP to increase his DPS, it was pretty amazing how much DPS the warrior could do. If you don't taunt and don't have any offensive proc weps (ykesha, snare, stun, etc) you won't take aggro from a monk using an Addy club. Its dangerous for the war but I have noticed it increases their DPS quite significantly.
