The games are way too long to not have a forfeit vote. Once competitive comes out we will want to be getting through as many games as possible. No one will want to sit 30 mins through a game where someone on your team went afk or is trolling.

This is definitely something we're actively looking into currently and want to accommodate to some degree. More on this in the near future!

We also have some AFK/DC features in place currently, that if another player abandons the match we'll reward your team with perks to try and even the odds. We're also looking to deter abandoning matches with penalties (and more to come).

All that said we want to be very mindful of our approach to letting you abandon matches, as we don't want to encourage giving up when there's reasonable possibilities of swinging a match back in your favor and being able to ride the high of overcoming the odds. Hopefully we'll be able to strike a balance, and everyone with differing opinions will come together to like where we land...
