riot has thought about this system. but they believe that it will increase dodge numbers substantially. i don't know if you were playing before they instituted the penalties. but you could get into three or 4 games and waste a few minutes each time before they instituded the current status of things.
that said. the ragers/flamers in ranked are a problem. teambuilder is the first step. they're going to acquire data from that and see if it can be applied to ranked in some way. but it's not an easy task.
personally i think ti would be really irritating. but i'd rather deal with that irritation as long as it's only for ranked. i like hte idea of a dodge bank where you earn your dodge like in aram with rerolls.
but it will increase dodging a LOT.
on sunday my friend and i went through 9 dodges/not join queues/refuse to joins in a row before we got into a game.
that would become more commmonplace.
i think riot looking at applying teambuilder to draft playstyle is more appropriate.
you select a role/several champs maybe a lane and queue up.
we'll see what their current teambuilder experiment learned. hopefully they will find that that is a viable option.
