Not sure which class - It's been a while.

Sup all,
Played in vanilla, was a big noob but have a fairly accurate handle on vanilla pvp. Gladiator in WOLK and TBC.
One of the main reasons I am coming back to vanilla is to do the pvp grind. I was only 60 for a short while before TBC came out and I really idolized the guys back in vanilla that put in the hard work. I'll be solo queuing grinding AV and the other BGs and will get a starter gear of "pvp BIS" blues from dungeons of course.
I'm struggling with faction and class. I want to be self sufficient and also just wreck people. As a warrior, I know I will need to make friends with some healers but I don't think that to be a problem. Something about a full blue set of gear and an unstoppable force really makes me happy, haha. It's like the one WoW achievement I was never able to get.
Anyways I am really looking for help with choosing the right faction/class.
1. Warlock (Horde only for Obvious Reasons)
2. Mage (Horde or Alliance)
3. Warrior (Horde or Alliance)
4. Shadow Priest (Undead Only)
How is the realm balance and how are these classes fairing in random BGs / solo questing+farming at max level etc? Hoping for some well thought out answers here. Thanks!
