Why does one mistake @25 minutes give you 50-second respawn timers and cost you the game?
I can't tell you how many times I've watched as the ADC or support or someone gets caught out at around the 25-minute mark, and they die and rest of the team gets engaged on and then it's either Baron -> Inhibs -> GG, or if you get aced it's just a straight run down mid with 4 towers and an inhib getting slobberknockered before you even get a chance to respawn.
It's pretty tilting to play so well each game, only to have one mistake on your team cost the game.
