But there are things that are completely uncontrollable and straight up nobody's fault, and those are luck. Imagine the following:
Blue team gets into champ select and has 3 top mains, a jungler, and a support. Luckily, one top main can do lissandra so he takes mid, the lowest guy in pick order pole takes an ADC and just hopes to survive lane.
Red team has a top main, Jungler, ADC, and 2 support mains. One of the support mains tends toward high damage mages like zyra and annie, and can easily shift to mid with only small adjustments.
Red team now, through luck alone, has a distinct advantage because: both tops, junglers, and supports are comfortable. Both midlaners are on comfort champs but not their preferred map areas, which means they can play well but may not fully utilize the map position. still even. However, red size has a comfortable ADC while blue side is largely unfamiliar with his champ and spot.
Therefore, red team has a built-in advantage, though far from a decisive one, before the game starts. Note that this is with all ten people being friendly and cooperative, which never happens and whichever team gets the whiner is usually in trouble.
Another example: you get into champ select. you're third, and in promos so you can't dodge. last pick goes:
"Mid ekko or feed"
first pick bans ekko.
"WTF now im feeding nub"
first pick" come at me bro"
neither will now dodge because fight mode is engaged, and the other two are a never say die never surrender duo, so no dodging.
so here's the question: What skill have you failed to display by third ban that could have or still can salvage this?
