As someone who has been playing warrior primary for a very long time, I have to say Warrior DPS is fine in most cases. You simply have to put the effort in to learn how to use it.

First toon was W/k back in chapter 1. Damage and defense was always very good. Biggest problem is that it's not an FOT class, so few players understand how much a warrior can actually do.
As mentioned earlier, more warriors make more damage, sadly there have been times when I have played for weeks without seeing another warrior that played as a warrior.
Side note, used to love it in siege when an r/? would shadow prison me, I'd start spamming moon cleave or blasting cyclone as soon as it hit, I normally had enough HP to take a few hit's and that rogue would be dead and asking wtf happened.
