Arena. Help.

As you all know Feral has gotten a great ginormous buff since Wotl. So has the pally healing class, shamman Etc. Now I have been thinking about going back to my roots and playing with a disc priest but i'd figure i'd play with a Pally First. Soo i played about 10 games, got to 1600. And i noticed that really Does everyone have problems with, Holy Pally/Hunter? What about the comp of Ret pally/Holy Pally (Pve Geared Ret pally(Pvp geared holy Pally). You have to blow beserk to make them blow there bubble, and then what? IDK, it seems like everything i knew about arena in BC has changed, and i need to relearn. Even though yes, My gear isnt that great (Been 80 a few days), And my pallies gear wasnt Great (Savage). But still should i be rollin with a Priest? Maybe a shamman?.. Give me some ideas.

I tried it with a rogue a couple days after, when i had a few noticable upgrades. (Weapon,Valorous peices, Some deadly peices as well). And well, it went better then i had thought. I got to 1700, Ezmode, Really its all about zerging and timing your Maim/KS/Bash on the healer or dps to make a good Kill. And the fact was my Rogue was in mostly blues, with the exception of daggers from Naxx25(KT). We did pretty good, Im going to give it another shot this week, since he has few more peices of hateful, and deadly off peices.
