The comp definitely has the capability of 2500+ ratings.
Your druid should be controlling the other team ALOT, while keeping hots up on you. If you guys rotate fears/cyclones/roots along with your cooldowns, you should be able to survive long enough for your warrior to get a kill (don't forget to switch cyclones if you're close to a kill and need to help him out!)
Hopefully thats at least a little bit helpful.
Edit: Sorry, thought you were the priest for some reason. Your priest should be the main dispeller and should stay in a good position to keep you dispelled if you get stuck somewhere, or you might just have to make a switch to something else.
