It's only the good Warrior/Pally teams that beat us. It's not like my previous arenas where Warrior/Anything raped me. Here's usually how it goes.
Warrior charges priest, I immediately CS so the Priest can start making distance. Warrior eats some damage during stun, then intercepts priest. I KS, Priest can now get away and load the Warrior up with DoTs. I Blind the healer, trinket, fear. After the fear runs out, the Warrior is usually at around 70% health or so, and both of us are close to full (hard for a Warrior to take down a shield getting stunned and kited like mad). I pop AR, and we start the mad DPS rush. Priest silences healer, health usually drops down to ~20% if the healer isn't a Pally. Pallies can bubble off the fear and keep health from getting out of control, but usually don't for some reason. It's now a contest of who's better, the healer or our combined DPS + Silence + Wound Poison. We usually win.
Now, if the Warrior is smart (or playing risky), he'll target me. I'm not AR/Prep, so after my 15 seconds of Evasion, I'm pretty much ******* The priest, on the other hand, is free to fully dot up the Warrior and even slap a couple on the healer to keep pressure up. If I can survive the Warrior's onslaught long enough, Blind + Fear + Silence + Wound Poison gets the better of the healer. It's a slowly losing game for a Healer against S.Priest + Rogue, and well timed silences and amps make this an impossible fight. It's all about me surviving long enough to get the killing blow.
Picking up my S3 chestpiece next week, hopefully a mace from BT or TK as well, then I'll grab the S1 OH mace and go AR/Prep for my arenas. We'd be in the mid 1700s easy if I was properly specced. We lost two games we should have won due to Rogues getting crazy mace procs. Nothing is more frustrating than getting a Rogue to 5% health, then getting mace stunned as I'm slamming my Eviscerate button, only to see a swiftmend take him back to 50%+.
