Get on the Shadow Priest as soon as possible. If your opponent is Alliance, be careful of Perception, stay next to your Priest at the starting zone and wait out Perception's duration. When you feel it is safe, the Rogue should walk out to give a 'path' to the Priest for him to run out. If your Priest does get Sapped, get ready to intercept the incoming Shadow Priest. Once you are on the Shadow Priest have your Priest Dispel whoever has Fear Ward, then continue to go on the Shadow Priest. Give your Fear Ward to your Rogue, hopefully he doesn't get Sapped so the Shadow Priest can easily dispel it. If the Rogue is on you (Priest), Dispel his Fear Ward and then Fear him. If he is Undead brace yourself again.

At some point you should be walking to the Shadow Priest, spam Dispel on him and his DoTs and keep yourself topped off as much as possible. Time a stun on the Priest so when the Rogue has his WOTF down you can Fear him without fear of it being dispelled immediately and he would have to trinket to continue on you. Blind him if he does trinket. If he doesn't, PI yourself and get as many Mana Burns as possible on the Shadow Priest while continuing to Dispel him.

If Crippling wears off run away and get as far away from the Rogue as possible. A key thing here is to not get Feared. If they go for your Rogue, avoid Fear from the SPriest and help out your Rogue by Fearing the Rogue that's on him. Your Rogue should save his Cloak when you are decently low (40/50%) so Wounding is off and you can heal him up decently. This game once again depends on how coordinated you can be and they can be, so be sure to have good timing and think one step ahead of them.
