If PreSeason 6 is going into this fast paced meta then can I suggest 15 minute surrender?

A lot of talk about how people think Season 6 will become this fast paced, stomping, carry champions only meta and whether or not I or anyone else who plays this game agrees or disagrees if Riot decide this is what they want as final then all I ask is to please consider lowering the surrender vote from 20 to 15 minutes like ARAM.

The longest time my games have been in PreSeason is about 30 almost 35 minutes but 80% of the time been around 20 - 25 minutes win/loss. I will say my experience from Season 5 and this past patch I've been wanting a shorter surrender time for a whole year because the games where you get stomped and there's nothing you can do or your team can do and instead of playing you are looking at the clock and reading the rage spammed chat maybe even jumping in on it to pass time it doesn't feel like a game anymore it feels like a chore, your motivation of winning has gone and honestly everyone just wants to leave and move on but waiting for that 20 minutes feels like an eternity and when someone doesn't surrender vote out of 3 already hitting YES because there was 1 kill claimed right after 20 minutes it makes it worse.

I know games are NOT always decided in 15 minutes but the games that are well... they're pretty damn depressing.
