Full DoTs on both the Rogue + his partner, Fear liberally, and hope something buy wow gold dies.Spellstone doesn't remove poisons. Most of the "how to kill a Rogue" topics here are really bad.

basically against a rogue / Disc priest its almost always auto-lose, its just because your main damage is from DOTs and with out UA the disc priest will just dispel them off, not to mention the rogue can COS and just wipe himself clean, coupled with a few fast heals from the priest and you're pretty much back where you started, with less mana.

Anyway, from experience (although we're in the same bracker 1700ish, and I'm UA and I run with my brother who is a SPriest) there are a few things we do that you might help.

If the rogue goes on you:
* Your SPriest will be your saving grace, he needs to keep shield up on you, and drop buy wow gold Prayer of Mending and Renews on you (Yes he has to shift out)
* Since you're SL/SL you can probably out last the Rogue and his cooldowns so your best bet is Drain Mana and Manaburn the priest.
* try to get a fear out to get some breathing room, in dire emergency your priest should run in and psychic scream the rogue off you, or trinket and deathcoil then fear.

If the Rogue is on your SPriest:
* Tell him to run and LOS the other priest so the rogue gets no heals and is forced to COS from your dots
* Fear the Rogue off your Priest to give him breathing space, then Fear the opposing priest when he comes close, if they both come close together, your priest should use his Psychic Scream.
* He has to shift out again for PoM and Shields and Renews to survive the rogue onslaught
* Searing Pain is your friend! When you see your priest can take the buy wow gold  rogues damage and the opposing priest is feared, hit the rogue with searing pain as many times as you can to drop his health fast! His priest will have to run in LOS and try to heal him, that's when you drop silence then spell lock then fear, and kill off that rogue!
