We need a all mid map that is not random.

If you want ARAM, where you can pick you champion - find ABAM/ADAM in custom games. And if you can't find it, then apparently people don't like it. ARAM also started as custom mode, but it was so popular, that Riot created matchmaking and special map for it. And still we had to ask them for years for it.

This logic is awful. Nobody plays ABAM because the games end up lopsided as fuck. You cannot make 2 coherent, balanced teams in a custom match, it's almost impossible. Nevermind the typical custom game problems like startup time and leavers/AFKers. That's what matchmaking is for.

And besides, what HA needs is Blind Draft, which is also not an option in customs.
