How to Fix Early game DC!!! Suggestion

Everyone encounters those games where before you even get out of the fountain your at a disadvantage because one of your players have a toaster at their house. This is unacceptable and i believe the following would solve the DC problem for EARLY game.

Solution: Once draft is over and everyone is in the loading screen, individually each person should encounter a connect button once they have connected %100. If said button is not clicked by all 10 people in a five minute window(or warmup) the game is considered abandoned and everyone is put back into queue. (play one game of CS GO for reference)

Problems:

1. Someone could see that their comp isn't really the best and turn off their internet.
2. People encounter problems during load screens and could connect later 3.?

Problem Solutions:

1. We already have leave buster for dc and afk punishments. Same punishments should be in place for the person who did not click the connect button. (CS GO starts at 30 min ban, then 2hr, then a day, then 7 days, etc.. )
2. Problems happen, (BSOD, firewall error, etc..), but this shouldn't effect the other 4 people on your team because your computer is having issues. Also you probably would prefer a cool down instead of losing LP for a game you didn't even get to play.

To tell if a player is DC at the beginning of a game is already implemented in LOL(They will move to the middle of the fountain) but does nothing to help out the other 4 players stuck at a disadvantage. I believe everyone would like a better system for the DC or AFK peeps and i think this is just a step in the right direction.
