three shamans vs 2 shadow priests and a warlock

[BIGBADPRIME]

I am wondering what team is better for pvp 3 elemental shamans or 2 shadow priests and a warlock (demonolgy or affliction). I think that demonolgy would give you some tools to deal with a rogue on physcial damage basis when he pops cloak of shadows. Now 3.3 made some cool changes i am wondering how this pans out. Dots sounds so much better now.

I am intending these guys for pvp battlegrounds and hopefully areana

Well i am looking for feedback here, who knows maybe i should just try the ptr but i find its good to find the advice from people who know and play these.

Half the reason i am asking also is my teams will take some leveling to equalize levels out also and its best to ask the experts. Since i know this board is a troll free zone, just like fox news has a no spin zone (lol i had to say it).
