Not allowed to have fun in ranked ever
Last game I played shaco and I was telling some jokes to everyone. The enemy team thought my jokes were great because they're all league puns, no offensive jokes or anything. I was still playing, securing objectives and assassinating the enemy adc and soraka support. The end game was like this:
My whole team was angry and wanted to report me for "intentionally feeding" when we had a 8/14 or something lucian adc that ulted thin air all game. Now I recognize my deaths were fairly high. I had only myself to rely on securing kills in a comp that had a lot of mobility. I certainly didn't play shaco WELL enough to carry, but the enemy team recognized my efforts as the highest contribution to the team in terms of threat level. The enemy team thought I should have been honored for being so nice and they also said I carried in terms of I guess whatever valuation is used to determine that.
I wasn't cocky, I didn't compare #$%^ sizes with anyone, but everyone else was waving theirs in my face like "SEE MINE IS BIGGER I'M HIGH ELO" telling me I was trolling because I wasn't "serious" enough. I did my best to keep my spirits up. I could have raged, argued and had a miserable game but I wanted to enjoy it for being a game. Not all of my decisions were great. I know that. My chat was clean and I was trying to not be that guy that points out mistakes.
The sad fact of the honor system is that people don't want to honor in a game where they are the losing team. Some people might, but instead of "Nice try shaco, better luck next game" it was "report shaco for intentionally feeding (not carrying the game)".
As a player who is often negative, trying to overcome this pessimistic attitude is difficult when you're accused of trolling every time you aren't being a total jack ass in chat. You say something negative, they jump down your throat. You say something positive, they still jump down your throat. You say nothing at all and they spend the whole game accusing you of intentionally feeding anyway.
