The only reason I can think of for the limit is to make it difficult for people to cause trouble anonymously. However, having 7 or more slots per account already makes it difficult to keep track of who's who. In my opinion, raising or eliminating the limit would only make the game that much more like the original. We adapted to people having multiple accounts back then. I, for one, don't mind having to adapt my tactics or intel gathering. It makes the game more challenging, A.K.A. more FUN!
