Some custom LoL-gamemodes use Draft Mode for selecting the champions. Both teams ban champions, that are not autobanned in the gamemode, and then pick allowed champions. In some gamemodes, there are restrictions on the pickorder.
Leavers in Draft ModeEdit
If someone leaves in Draft Mode, or the game has to be restarted because of a client/server bug, the teams should ban and pick the same champions they picked before. Otherwise they're just gonna ban/pick the champions the other team picked.
