A question about the new MM and rank system for next season.

let me give a few scenarios here.

>bot lane goes 0/14 at 7 mins.

game is unwinnable

>jungler refuses to gank mid because mid didnt leash. mid responds by running down mid.

game is unwinnable

>jungler decides to gank bot 3 times and feeds double buffs to enemy ADC 3 times. enemy ADC promptly snowballs

game is unwinnable.

>Support decides to afk after going 0/1 because ADC didnt heal her/him. enemy team recognizes this and promptly 4 man tower dive the hell out of the now solo lane ADC.

game is unwinnable.

How does the new system solve any of these issues? i cant speak for anyone else, but personally if i am playing well then the only "reward" i need is a win. dont care about shiny boarders or whatever else the new system is going to give you, all i care about is being able to WIN a game that i play well in despite the actions of one or two people... It is insanely tilting to lose games that you set up for so perfectly in the early game and mid game but still lose because you let go of your teams hand for just 2 seconds... and thats all it takes, two seconds and someone just got a quad or penta for literally no reason what so ever... and now you lost baron, dragon, and all of your map control and inevitably the game simply because you wanted to leave your team and buy items...

how is this being addressed?
