That so sounds like me lol....So I played that to level 19 then made a mage, got that to level 52... Made a Orc Hunter, got that to a really well geared lvl 28. and a buncha other alts that are levl13ish-20ish.
I had a 28 NE hunter 1st, then a million 14-20 alts. I quit WoW and then I realized Horde was the place to be so I made a Troll Hunter and got him to 44, then quit. Then got back into WoW and made a BE Pally. He is my highest character and my main. A whopping lvl 58 lol. He has lvld about 3 or 4 times in the last 5-6 months hehe. Im a very slow leveler at high levels and I'm waiting for my payment to end, it's up till this December but them I'm probably done for good.
