"Why? Because I can."
Does anyone here feel like the words "Because I can." as a reply to "Why are you playing ranked if you won't take it seriously?" is the most toxic thing you can possibly do in League?
Hate speech, just mute 'em. They won't bother you no more. Griefing, just report 'em. They'll get the hammer soon enough. Inting, report 'em. You had no chance to win that from the start. But... "Because I can"...? ...it's extremely toxic because you could actually possibly win if he took it seriously.
You accept your fate with a griefer, intentional feeder or a toxic player... but with someone who just doesn't give a fuck, you can't - because it's so winnable, and you see it. The win is hanging right in front of you, and if only he'd help you grasp it.
But no, you have the super indirectly-toxic Warwick player AFKing to take phone calls or take a dump or make a snack, and then replying to the incoming criticism and questioning for the totaled 25min spent AFK with "Because I can and you can't do anything about it."
