Hm, I like this kind of thing.
With these kind of events and then a League Of Legends (alike atleast) mod, with spells (4 abillities), classes/playertypes without jumping and jet (types, like melee, caster, support, tank and so on), a map (already started to build the 5v5 from LoL).
With this typ of gamemode you could make a DOTA game-thingy
