I think it would work better if you had 2 teams, the defenders and the attackers, attackers activate the crystals too begin spawning the minions, defenders have to hold them off, of course to remain fair there would have to be less attackers than defenders or the attackers could basically just zerg rush the base until they won, although to counter that you could give them a certain number of lives and if their team ran out when people died they died until the game ends, the game would end when all attackers are permanently slain or the nexus goes nuclear, defender team could be around 7 or 8 player while attackers would be half that number for balancing since the defenders would have no minions, also attackers could spawn at level one and defenders at level 3 or 4 or so, that way the minions wouldn't be rediculously strong against the champions, with this setup it would be a more competitive style (which is kind of what RIOT wants) but it would still be fun as something new to do, I quite like this idea myself though with a few tweaks like I mentioned, some others would further improve the experience for the players and in a way you could even find a way to tweak it to have its own ranked mode (though I doubt it would be the center of any major tournaments unless it really caught on, notice how 3v3's are not the default for any well known tournaments despite being in the game for a while and even having a ranked mode that is well thought out)
