in response to antonis, the game will only be more competitive next set if the other gangs are smarter and more organized and keep up with MIG from the get-go. once MIG gets a good enough lead, there's no looking back and no catching them. yes, all the top-ranked players are in MIG and yes, those same players will more than likely reform in MIG next set... but there's nothing so special or magical about them that they will automatically do better than everyone else... what it is is that these players have a solid understanding of the game and know exactly which crimes are best for them to do to raise cash and levels quick so that they can get off to great solo starts and then they come together quickly and organized for the gang crimes, hitting your BLCB all the time once they're capable of doing it.
technically, any of those other gangs could do the exact same thing if the players played with enough strategy. but since nobody starts off knowing everything, it would be up to a competent gang leader to make sure that gang does what it needs to do. it's as simple as that.
I'm sure gangs 2-5 also have a piece of what it needs... but they probably don't have the part where they can have 3 teams doing BLCB all the time... or even if they have that NOW, they didn't soon enough, and that's why they have no hope of catching MIG at this point.
