to fix AI u do 3 things:
remove AI from the game.
allow shared control of players that have left.
With no AI there is nowhere to experiment new builds and noobs bashing would he so easy. U will get poeple who wouldnt know how to use shop or what does right click do.
Shared control would be very hard (except regulus sniping from crystal) i cant imagine it working
I was thinking that game can pause when someone leaves and enemy team would have dialog shown saying something like: One of the users crashed, You can finihs the game without stats recorded, or one of players on team can leave to even numbers of players in both teams and continue the game.
Say u got 3v3, one drops, enemy team have option to end game with no stats record or drop one of their players and continue 2v2.
