Kda doesn't determine if you're having a good game or not. I recall a Fiora top game I had. I wanted mid, but some kid cried about always having feeders lose mid, this and that. Well, leaving lane I was 3-0 with both the enemy top towers taken, and the talon was like 8-4 or something like that, but had none of the enemy mid turrets taken, all the while losing his own turret(s). Skip ahead a while into the game, I ended up being like 6-7-5 or something of the equivalent with all 3 of my opponents top turrets taken, damage to the inhib, plus I took both mid turrets while he was roaming for champion farm. I had 240 farm to his 190. I was level 18 with a near full build, and he was level 16 also with a near full build. Talon was like 19-8 or 20-9 (something like that) at this point. One more team fight and we would've won, but the talon decides to rush in 1v5, get decimated, and began blaming me for not following. We lose the game. Talon cries "Can't carry everything". I proceeded to tell him kills don't win games, towers do.
If your teammates are doing horrible kda wise, but are taking towers, don't blame them. It's time for you to step up and take responsibility.
