(New Game mode) Battle-Camp
The entire point of this game is to provide a fun mode that lets everyone reach full build easier. It also establishes good playing habits, and rewards teamwork. It could work not only as a seasonal game mode, but even a training method for unskilled players.
The premise is that there are objectives which give you large amounts of gold. It would work by giving players simple commands like placing wards in certain areas, attacking a tower, grouping and going mid or jungle, engaging team fights, Defending your base when one of the three inhibitor towers is up to fight, etc.
Everyone has a circle around them. It appears green for teammates and red for enemies. When you get close enough to another teammate, your circles join. The distance of the circle is based off attack and ability range. When 5 teammates are together, the circle glows two or three times as bright. Maybe some other added effect with that.
The main goal of this game mode, is to condition players into picking up good playing habits. While being fun and allowing fast paced, more balanced and rewarding game-play. There could even be an option like, battle camp suggestion after game. After someone gets so many battle camp suggestions, they have to play it. Once a player has forcefully played 3 battlecamps, they don't have to anymore. Or if that sounds too abrasive, after bot games new players must play 3 battlecamps.
