I don't think the people from my last game were adults.
Mid was 0/1, jungle was 0/1, bot was 2/0, I was 1/1
Lucian gets 2 kills then before recalling, pushes the wave in to reset the waves and get some experience advantage at which point our jungle decides to start a fight, which our mid joined despite their jungler being 2/0 and obviously they start getting their asses handed to them.
As God intended, they both die.
Dying 2 times in a row didn't set well with mid so he starts pinging question marks (btw, the most toxic and useless ping ever, never actually used for MIA) on Lucian, i don't know why but the support also starts joining in. Now, Lucian gets tilted and says "Ping me once more and I'm out", our mid spam pings
"Lucian - Alive" (btw also pretty much useless other than contributing salt)
"Oh well", our mid and sup stands at base and keeps using their skills on an ally, dc-d Lucian. After another death, the jungle goes afk.
And there we have it, in a span of 20 sec, a winnable game turns into a 1v5.
