kda dont mean anything. That adc kda could totally be explained by something like: hes tryign to do his job, but you never initiate, never peel, etc. So its your fault really. team game bro, do your role, ignore kda.
when i play adc i have games where my kda is like 9/0/6 and i have games where its liek 1/11/3. im the same player both games. Im doing the same stuff...im not being stupid or crazy or anything. Know the difference? basically its whether the team will initiatiate or peel...whether they will group at all...whether some enemy assasin got fed (not usually me the one feeding him) etc. Not totally my fault bro. Sure i coudl avoid 11 deaths by never leaving fountain, never farming, etc...that what you want? think about the team and what is going on, not kda.
