Need help choosing between shaman, necro, enchanter

[mjg]

Used to play on blue, but don't have as much time to play as I used to and I can't decide between shaman, necro, enchanter. Might use one of these chars to farm a secondary melee toon in the future.

I'll most likely be soloing most of the time but would love to raid end game content as well and farm stuff for a secondary melee toon in the future. PvP ability not that important to me. I lean shaman but feel like the journey to get torpor will be difficult and long.
