Just a suggestion:
I dont really thing blizzard would ever ask for a MAIN character name.
It just doesnt make sense; how would they determine which one is your main?
If you had 2 70's, then that wouldnt make sense to have a Main (i have 3, and i dont really call any of them my main)
In short, its probably best to take out the part with Main Character name and server, IMO.
Feel free to disagree or reject it.
