Dual Boxing is for quitters?

Why pay the extra money for another account? Let me be your other box. If anybody is thinking about lvling up a new char, let me know. I am looking to start back up in wow but i gave my account away when i quit. i'll run around with you if you don't feel like paying for the extra account. I just don't think i can handle grinding my way back to the top. On a different note, where are all the second accounts going? I plan on dual boxing a char up when my account gets to two months but what are people doing with them when they are done?
