New game mode

They should make a game mode with a constant six people in it. But add an extra tower to each lane and in the base. Expand the jungle territory and add new and more monsters so you have a harder time getting through things. Increase the level cap to 21-25. Depending on difficulty of the laning phases and how the cooldowns work on jungle monsters. Add another new map boss like Vilemaw and Baron but have it be twice their strength and have a better buff that empowers the team that obtains it.
