Found my 58 warlock from TBC horde on alliance realm

[69 Arms Warrior]

found a 58 warlock from when i tried to play TBC and boosted.
All the gear is garbage, I have 20g, auction house has 0 glyphs...
but im horde on an alliance dominated server.

Should I do affliction or Demo? for the 59 bracket and world pvp.
