5v5v5v5 grand melee map. Special beacons to allow teams to truce with each other for 5 minutes at a time. Rally flag carry able as an item that allows teammates to teleport to the flag (can only be placed in uncontested, owned territory) from a beacon in base.
Capture able turrets like dominion in contested territory. Day time/ night time changes, with the days growing shorter as the game goes on, exp bonus during daytime, exp gains decreased dramatically for night time. After 25 minutes epic monster spawns in map middle during night time only which gives, say, baron buff plus blue buff plus red buff to all allied champs who kill it, multiple teams can fight it together and it's toughness increases based on the number of teams initiating on it.
After 40 minutes if the epic monster has not been slain once he initiates the "long night" and becomes mobile, attacking whichever team has the most income/towers/inhibitors still up. Turrets will target it and it can be slain while mobile but you receive no buff for killing it during the long night. Each team gets only 2 bans.
A victory as a single team counts as 5 points, as two allied teams is 3 points, as three teams is one point, and destroying a teams nexus earns a point. Karthus is perma banned.
After 50 minutes a new shop opens up near the epic monster location which allows you to combine any two items into a third item that retains (most, if not all, tougher with activatable items) of the two items' qualities in one item, allowing players to further increase champion strength in the late late game.
If all the central area dominion towers are captured by one team that team now spawns a trebuchet minion in waves that have a cannon minion and this new minion does mad damage to towers.
