Drop elusiveness, ghostly strike and initiative. Get master poisoner(1-2) and imp poisons(3-4). You don't use nearly enough openers for initiative to be useful, and ghostly strike is just awful with daggers, 20 more energy for a mutilate is so much better.
Gaining the poison talents also make it harder for druids to get rid of your stacks, as you are applying them quicker.
Your primary job will to just stick to the warrior, while your priest will LoS him and play with the druid. If your priest can't survive a warrior, you are basically stuffed.
I do 2v2 with a shadow geared disc priest that has a rogue main and we have broken 185o. With a full vengeful geared priest you should have it much easier.
Fear the druid every cd, every single time. Force him to want to heal that warrior, waste his mana, wound will be up, you will be stacking stupidly quick, and jsut forcing him to play your game. If wound is not up enough, you will most likely lose.
You need to be aggressive, shutting down the warrior immensely, and when the appropriate time comes(druid should have trinketed by then) a blind+fear combo can be deadly.
You have 2 options. If you think the game will drag a little, do your cold blood early on to force the druid to panic heal.
If you tihnk you can quickly take the warrior to low health and cc chain the druid, then save the CB for that.
Our usual loss' to warrior/druid is what you said as well, warrior goes and lolstuns my priest and by the time he is out, he is dead.(intercept+weapon stun+mace stun = GG priest)
I usually try to save my KS for when the warrior does his intercept, and if that fails quickly try to gauge to buy some time so he can LoS again..
/edit*
My priests spec. The imp fear is nice, and blackout procs surprisingly are a massive help at times.
Reflective shield is big against warriors(and rogues), as it eats away their health.
But this is an unorthodox spec, and some priests love it others hate it.
