So let me just explain with some background information, when playing league there's often this one person that doesn't say what he wants until it's his turn to pick, sometimes 2 people called solo but they didn't know it of eachother etc etc.
Sometimes there's just not enough time to plan who picks what role and which god, which is why I want this:
Overtime: Each team has 45 seconds overtime, if a player doesn't pick his/her god in the regular timeslot, the overtime will start ticking. Overtime does not replenish during the lobby, this means that it'll only make the lobby 90 seconds longer, AT MOST. the overtime will help battle the too large amount of DCs in lobby because they didn't have enough time without making the lobby too much longer
Pretime: Pretime is very simple, each team gets 30 seconds to talk before the bans begin, during this time both teams can discuss what they want to pick, ban and decide who gets what role. these 30 seconds will allow more focus on the ban stage and make league games a bit more enjoyable
