I'm prot warrior #2 in my guild as well, working on Archimonde and Bloodboil in BT. On fights that never require me to be tanking something I'm in my dps fury gear, switching stances to lay down TC and Demo. I do 700-800 dps in a non-windfury group but also provide a battle shout buff to our 1 or 2 other feral druids who are also dpsing, increasing their damage. While I have a lot of PvE gear for my dps set, a good chunk of it is from PvP and I run ZA for our guild every weekend, using dps gear from there when available.

As a prot OT you should ensure you aren't gearing like a MT. While you still need a healthy amount of stamina you should focus on avoidance stats as it's a great help to healers to take less damage overall, while still being able to survive burst damage.

Always keep in mind warriors are supremely gear dependent and you have to make the right choices to be effective, especially as an OT. It may take time but in my mind, and that of my guildies' and RL as well, I am as effective as a druid OT.

Breklin,

I'd certainly like to see what gear you're using to achieve those dps numbers as a prot warrior. My understanding about switching gear has always been that even in impressive dps gear, a prot warrior is light on the damage output.
