In that case... Should I delete the character from my brother's account, and give up with multi-boxing for a while, and later on purchase the battlechest + create a new account? Yes, I could purchase the battlechest when I hit 60 or 70 but it doesn't matter that much, I should buy both within a week anyway from opening the new account. Not in a mood to start fighting with Blizzard if they decides to ban both accounts.

And yes, with RAF it's pretty swift anyway, I'm not going to play rich-and-poor, got too much to lose on my own account.
