I've finally decided on my second team. It's going to be PVP focused - battlegrounds only.
I've decided I'm going to roll this team on a PVP server just for some world pvp opportunities.
It's going to be a long haul as I'm not going to RAF it this time, but I do have a 69 pally and a 55 priest on that server
I can use to instance boost/ support.

Levelling wise the locks are going to be affliction. I'll probably respec to holy or discipline.

I don't have a clue what spec to go come 80. I'll dual spec for sure

I love affliction - having a very mobile team with powerful dots sounds good, and i'm hoping the teleport ability
might help out to get away from pesky melee. One fly in the ointment would be the priest. No teleport so I would be leaving him to face the music. Then again howl of terror, deathcoils and psychic screams might allow me to only have to teleport from bladestorms.

Then again I think demonology could be good too. 4 x felguard + demon form and immolation aura, with a disc priest spamming holy nova might make melee trivial, and cut through casters.

Destro I've never got to grips with from the old days pre wotlk. I think it will have insane power, but what options do you have to get away from melee. Suppose you still have teleport.

So the only thing I would like feedback on - Those with practical experience of lock teams, what's the spec you run with in BG's and why?
