the idea is to the laning phase into mini game that will give new players a foundational understanding of the game that they can apply to understand the game at large.
the game is 1 lane, 2v2, 2 towers, 2 pull camps, and maybe a bounty rune. Hero pool is limited to conceptually straightforward and balanced heroes, with the item pool limited and balanced as well. Games last about 10 minutes, you win by taking the enemy tower or having higher networth at the end of 10 minutes.
New players could efficiently learn important fundamentals such as pulling, starting items and skill builds that apply to later stages of the game. This way we wouldn't have players with 6000 hours who don't understand when to buy wind lace, magic stick, etc. in their starting items. The games would be more convenient for new players, a group of 4 new players could play their own game without worrying about 6 other wildcards. Smurfs would be dissuaded as they want to play real dota.
I'm no creator so im just throwing the idea out there. I think something like this mode should be an official playlist, maybe limited to people with sub 100 hours. Dota needs an "easy" mode and this is the closest thing i can think to it.
