So yesterday I was playing Jhin adc and I stomped my lane super hard. My support really didn't have a single clue about what he was doing he even admitted that he doesn't know what he was doing, he was playing Fiddlesticks and we still trashed their botlane to the point where I was like 2 lvls ahead of the enemy Ashe, who didn't do anything for the rest of the game she had the least damage in their team and she was overall just super behind the entire game. My midlane was losing hard tho, it got absolutely destroyed. It was my Karthus vs their Pyke mid. Our top lost hard too, but my jungler had over 20 kills so I was pretty confident about the game. I did end up having the most damage and the best kda ratio in the game, but we still lost the game. Why ? Because that Kayn that I had the most faith in decided to go for a baron when their midlane was pushing and so was top, and we had no vision on the map because our support had about 15 vision score. I told him that it was a bad idea and that we should just group mid and defend, but he told me that I was an idiot and that I should just shut the f*ck up. The entire team went with him to that Baron, so I decided it's better if we get caught as 5 and maybe not lose that hard, but we got murdered and lost the game in a single push with baron.
TLDR, our jungler made a stupid call ignoring me telling him it is a stupid call and we lost the game from that. I really want to know this. Is is okay to lose a game like this where you are really super strong and playing really well, but then one single call throws the game. Is it okay to lose games like this, or should I somehow pull through and win the game if I was actually a good adc ? Some one tell me this since it's been bugging me since yesterday.
