vs RMP, it's very difficult, probably the hardest comp to face. We always try to save CDs (bubble, trinket, etc) for when they CC my partners and go for me. Pretty much your only hope is to play very defensive until the priest starts running low on mana and start to own him
Also time your stuns/cyclones on the rogue when the warrior wants to BS
vs RLS, your paladin cleansing fear is very important. We usually stick the warlock/pet until he ports and goes away, then we make a switch to the shaman. I try to clone the rogue as much as possible, especially during kidney shot. Also, ALWAYS decurse elements.
vs Spellcleave, the only variance we have extremely trouble with is Priest/Mage/Ele and MLD. Very all spell cleaves, we spend most of the game defending. We los and play extremely defensive during lust. I also try to, at all times stay in a position where my warrior can intervene to me safely.
There is no real counter (I run that comp). We specifically train the Paladin, forcing the Priest to heal to make him refrain from burning and dispelling. The only real viable option is to go with a DK instead of a warrior to help with peels.
