Chloromancer is pretty fun, especially in battlegrounds.
Also, just an FYI if you didn't know, the beginning quests award you with your first 3 souls, but you can pick up quests in your faction's city to get all the rest. They're all the same, close a rift, use quest item to summon a mini-boss, kill. You can also buy extra slots like WoW's dual talent specialization, but there are 4 (I think) total so you would have a support, healing, pvp, and dps build and switch on the fly (while not in combat that is).
