I really don't think 3 mods are enough, it can't cover everyone's tastes, the insanely wide palette of skills toribash has to offer, all the interesting gameplay aspects the game can take etc...

Plus it's interesting to have a decent list of choices offering different "match strategy" depending on who/what clan you're fighting. Like, it would be boring to only have 3 maps on Counter-Strike, or 3 characters on LoL etc...
It's good to have a limited amount of competitive mods so it doesn't get messy and people don't get to play random fun mods they never heard of during matches, but it's not good to limit the players and the choices the game has to offer, we should still have a consequent amount of mods to choose from, I even think 9 is pretty limited, it could go up to 12 imo.
