I hate having to waste 5+ minutes total on a loading screen and barely the start of a game till my team remakes and causes me to have to start another match.
And honestly, a far better measure of not starting a match could be put into place instead of asking for a remake in a game which literally revolves around your team winning it's lanes.
Riot, I know you guys never refer to the boards but you guys can learn SO MUCH from looking at how CS:GO has always handled their games. Here's another example where CS:GO games immediately end if a player fails to connect. There's absolutely no reason to have someone wait 3 minutes prior to attempting a remake and games should end within the first minute if a player is detected to have disconnected or left the game by then.
