New BG/arena team

Hello again, im trying to decide some teams for cata rated bgs/arenas and im having the hardest time deciding what kind of arena teams to make, already have quad shamans, give me some ideas ty :D

I myself am going for either a 1 Priest 4 locks, or 5 priests, hard to decide.. both will have very nice new stuff.. priests have very nice healing with 5 priests if you want you can go disc/holy pvp or whatever you wish and hit like truck and heal very nice (Binding heal for example and whatnot alot of healing anyhow :)).. Locks have sick damage(instant soulfire and Doomguard and cool stuff) and moderate selfhealing add a priest to that and you have a scary team..

Read up on the class changes if you havent(bet you have:))

well i play 4 toons, and have a friend heal. i was thinkin 4 locks or 4 rogues but not sure, do the felguards do alot of dmg?

well i cant say for cata, in wotlk they hit ok, their charge is very nice too(charge stun is nice) Metamorphosis is really fun too! Destro is easy to box aswell, now when click is gon Affli will be alot harder.. Cant say anything about rogues..

While my 5 shammies are always going to be my favorite (especially with the new toys we got) I'm also going to love my 5 mages methinks. The main (my first 60 in vanilla) is 80, and the slaves are currently resting at 66. Got them all specced and glyphed this morning and started playing around on dummies, and I think a 5 frost mage team is going to wreak havoc in open/bg PvP. Shammies have 20 totems, frost mages have 5 water eles, 15 mirror images, and that new ring of frost thingy. When I popped my eles and mirror images I looked like a raid :)

My priest/locks I haven't decided yet. I haven't even specced/glyphed them yet because I haven't really been impressed with the new soul shard system. I'm sure I'll figure it out later though.
