Forfieting
As an honest to goodness idea for improving the game and making tilt less common might i suggest reworking the surender system just slightly. I.e. if not right away can we allow 3/5 yes votes to forfiet by thirty minutes? Please, it is very annoying to have three people who want to leave and either two peple who are either really stuborn or worse trolls that refuse to forfeit. If the game has not changed into the loosing teams favor by 30 minutes it likely won't and at that point draging it out is just making three players annoyed and or frustated and wasting everyone's time.
Please riot for the love all that is good and for a better game experience for the majority please... if not at 20 allow 3 to 5 vote to end at 30 or if you really want to push it 40 but please games that drag on are not fun for anyone.
