Yeah I took a look at your match history, and I see a huge lack of normals there, so you have an extremely distorted view on rage considering your high rank. So, let me rephrase:
IN NORMALS ragers are stupid and can't play at all and blame everything on everyone else on the team even though they're the ones fucking up and making mistakes, and the other players are actually doing pretty decently. They're always the ones to push out when there's no vision, when no one is with them, when the enemy is mia. They're the ones who can't see the glaringly obvious bad engages from the good and just go in constantly and blame their team when they die in a 1v5. They are, almost every time, the single biggest reason a team loses.
OP is doing nothing wrong frankly. Literally, he isn't doing anything against the summoners code, he's not being mean spirited, he's not being dumb or intentionally feeding, he's doing nothing wrong. He's doing something FUNNY to confuse ragers in his elo, and it works for him. Just because one person decides to rain on his parade and insist he's wrong DESPITE IT WORKING FOR HIM isn't going to change anything. Clearly, high rank isn't everything and with that comes an extremely limited pool of other players to gain experiences from, positive and negative, and therefore, a severely limited number of ways to deal with situations.
Rage doesn't need to be consistent, and it never will be. As was said before, ragers will find SOMETHING to rage about because they're pissed off whether it's a legitimate complaint or not. You can have a perfect score, and have been warding, and pushing towers, and been doing everything right, and a rager WILL STILL RAGE AT YOU because, despite you being top at the time, 'WHY DIDN'T YOU HELP ME BOT NOOB????' or 'OMG WE HAVE NO VISION, WARD YOU STUPID NOOBS!' when they've placed 2 wards all game, and you have the upgraded warding trinket and have actually been using it. Ragers, frankly, are stupid and don't think because they're angry. We all get a little dumb when we're angry. We become irrational. Which is why no matter how well you play, ragers will still rage. THEY'RE IRRATIONAL.
