I have a plethora of level 40-70 alts. Let me know if you ever need a hand with a run or something or if you need any materials since the AH is restricted due to them trying to shut down botting and I'll see what I can do.
Which one have you gone furthest with so far? Or have you just been playing a little bit of all of them? It's worth noting that once you get one character to 50 you can set them as an assist character and call them in to use a cube skill during dungeons on other characters, even lowbies.
