How do I do good in the game but my team still ends up losing.

For some reason in a lot of games if you checked my profile, I lose... a lot. It's not because I suck at the game (I do) but I always have rotten luck when it comes to these matches. I seem to do well quite a bit with top, mid... anything... and somehow later on my team ends up losing most of the time (excluding trolls and dc'ing players). Sure, I have my banes that I complain to the point I made a cringey post (the yi nerf one) but I can still do well sometimes. However, I just don't understand how I am still contributing well to my team and my team still ends up losing (for example me getting 27/6 as kai'sa one time) and everyone who checks my profile thinks I am the reason for everything (well sometimes I am). I need to find a way how to keep this from happening in future matches because I have a grudge against myself by looking at my kda.

Any advice will do, thanks![slayer-pantheon-thumbs]
