True that BBlair may be overhosted and overhyped because it's an old level that was very popular at it's time. One of the main reasons why many players like me still like BBlair is because there's little luck involved, in duels, the first player who makes the slightest mistake and gets roasted isn't almost always the one who loses, unlike Distopia and DW. BBlair makes it easier to predict your opponent and get used to his/her tactics.

I will not have a say on the top 10 since it varies from time to time.
