Crowdx,

I believe the limit to Battle.net accounts is 8 wow accounts per Bnet account, I have not reached that limit myself yet though. I currently have 2 seperate bnet accounts, I own both of them and I have yet to be suspended or etc. I would just make sure your information is exactly the same on both bnet accounts and make sure to update both of them if your personal information should change.

I currently play 10 toons, 5 on each bnet account, they are all at 72.
