I really suggest you dont keep the veiw that a kill for a death is worth, if your in lane your losing cs, if your jungle and you do this 2-3 times your really shooting your teammate in the foot, especially if they are not good with last hitting0, And thats assuming your getting 1 kill per death (your not). In your last 10 losses you have 4 games ya did 1 to 1 or better, 6 of them your kda was under 1 to 1 plus in only 1 game did you hit a 2 to 1 ratio. That is likely why some folks say your feeding, and in said games they are not wrong to say so. Looking over your kill participation %s and a few of your wins It looks like your a highly aggressive player, you go for the kills and you go hard for them, regardless of if you have teammates backing you up, Try to dial it down a bit, work on communicating with teammates, and if your behind you should work on freezing lanes, farming, and getting the gold from sources other then kills to help put yourself back into the game. For now id say work on getting up to a 2.5 to 1 kda and try to bring participation up to 40%s and one way might be dialing down the aggression. Works great when they don't react to it and let you snowball, but if your diving and dying because your going way to hard your gonna have a bad time.
