Cool idea!
Ironically it leaves the question about the
true carry open - because I doubt that a supporter would ever be considered as a carry here. I bet farm, kills, assist, objectives and so on will determine your score. That would leave supporters behind even though the Alistar could have been the one who's constantly getting the engages, sets the perfect wards just in time, makes the best calls, and so on. You get my point.
But it's still a cool concept if your DuoQ mate from Mid says he carried the game and you believe that you were the ADC who lead this team to victory.
Obviously some features are still missing out I guess. A breakdown on the score would be cool, otherwise Matthew from Mid will still think that he carried cause the score is clearly rigged
As minor changes I'd recommend to either directly show who were the carries (as theres nothing else to see anyway so far) OR get linked to this site when you just click on a bigger button, the whole box itself or atleast the champion picture. Because it's quite weird to always aim on that small arrow in the upper right corner.
But still, big thumbs up, I like this concept
Edit: By the way, the name is a bit confusing. You try to convince others that you carried (I guess that's what the concept is aiming for) and it says "Who Carried
Me". In my opinion something like "Who Carried This?" would have been way better. It's still in the likes of your name but it's funnier as it sounds more "all-daily" and fits more in the concept you're having.
And from a psychological point of view it's also more positive in terms of user experience, because it doesn't make the user feel like the bad guy. "Who carried me" assumes that everyone else except you did the work.
