King of the mountain/volcano (4v4 game type and map)

Why not have a Game mode like king of the mountain on a volcano like map where you have to fight your way up the mountain to capture defensive camps until you reach the top and hold it down for a period of time or until a certain point value is reached.

Each team would start at the base of the volcano where they would have to fight jungle camps to the first defensive camp. (by this time every one should be at least level 3) At the first defensive camp, no less than 3 champions the would have to channel on a platform to build a tower.(NOTE: First defensive camps cannot be destroyed or taken over.) After the tower is built it would aim at a rock wall that blocks the path to the next camp. after a short distance the map would open up into a Summoners Rift like jungle area where you would have to fight monster camps and Enemy champions to get to the first neutral defensive camp where the team who first got a tower built would control. (NOTE: Any Neutral defensive camp can be taken control (like the points in dominion) by destroying the tower and the channeling of a champion.

After a neutral defense camp has been taken a rock wall will fall allowing teams to move on their way to the next neutral camp. There would be three neutral camps and jungle between each. Each neutral camp would award points/gold as time went on.

After the last Neutral base would be an altar like throne where one Champion of your team would have to sit on and lock down after 60 seconds. The Throned/crowned champion would be able to cast abilties but not be able to move after the throne is captured. The opposing team would have to storm the throne and kill the throwned champion the take over the mountain/volcano. After a throne has been captured for a constant amount of time it would erupt ending the game.
