Depending on the fight and the gear, hitting over 1000 on a warrior isn't really that unheard of. As far as straight parsing on warrior (or a fight like faust) warriors are pushing the 1400 margin and with oppressor dps coming in around 1300 on the record high end and about 1200 for warriors. a2s is even higher due to aoe. a3s is around the 900 - 1000 dps range and a4s is around the 1000 - 1100 range.

So if you are strictly talking about a1/2s then 1000 is a bit low for a warrior. I'm currently doing 900 - 1000 on my drk in a1s with about 1250 on faust as OT. But obviously this is dependent on various factors such as gear and healer competence to allow for more liberal stance transitions.
