Considering the following

now unless it is past 40 min acing the enemy one team-fight generally wont win you the game if u are behind.

which means and most games are "decided" a good 5-10 min before they actually end

20-27 min games flat out means never every single game is decided before the 20 min mark.

how is that ok? what happened to 35 min games?
