How about new map?

Rito talked about this one, they would have to make a whole new engine to run something like that because the one they have currently only supports 2 teams

This seems pretty interesting actually. I've thought of the idea of having a 5-man free-for-all on the Crystal Scar, but not this yet... Strategy always becomes much more interesting when there are more than two sides! Do you wait for the other two teams to fight, then pick them off while they're weak? "Buddy" up with one of the teams to snuff the other out? Fight everyone and everything until you either win or lose?

Seems like it would be the perfect kind of mode for assassination shenanigans! And personally, I think this map looks great for 4-man teams. Then you get the choice of having either a jungler or a support.

The middle lane though... it looks very, very unsafe. And would there be two waves per wave there, whom would split up into each of the other mid lanes? Say, 2 melee, 2 casters, or would they alternate on where to go? Also, what is the motivation for even pushing mid lane? there's a HUGE risk that the other team comes at you from behind and wrecks you while you try to push. Especially if the other two teams are buddy-buddying. I think there should probably be something important in mid. A reason to keep it controlled. Maybe something akin to the points in dominion? A "Point" you capture that gives you a buff for controlling or something similar, or maybe even a baron or something?

It's an interesting idea though. I'd love to see it worked further!

What's to stop 2 teams from collaborating and snuffing one team out?

I think any ridiculous game mode like this would be fun but it would be impossible to balance, and Riot is all about that balance.

3 torrents would take too much time, i think that 2 towers each lane per team would be better. And would there be another jungle creep similar to baron/dragon? also, i don't think it would be fair if e.g green team would compete for baron as it would be too far for them. Also it could be a 6v6v6 instead of a 5v5v5 to make it more challenging/ less (choose where to send the support).

Also, another idea would be that there is only 1 nexus in the middle and the team who could last hit it would win? (kinda the inverse of the lanes)

that is a splitpushers wet dream right there

I love this map idea. Everyone up vote it now

What would happen when one's nexus would be destroyed? Game ends? Game continues with 5 persons waiting? Team sides with the ones who destroyed their nexus? Against the ones who did?< What about dragon and baron..?

i would go outside lanes only, 2 top / 2 bot for everyone leaving one intense jungle for the junglers, alot of warding needed, and gank potentials out the rear, although i fear this may render mages useless (but in aram mages are highly valued, each mode has diff metas and playstyles)

IMO more maps/modes = more happy

^^mai too sense
