Prevailing attitude of at least one (usually more) people every single game I have.

I'm a very safe player. I usually don't end up with huge amounts of kills. But I don't die either and my kda is almost always very positive. Been playing a lot of Ahri lately and people have started blaming me because I don't have like 15 kills. I may have 7-9 kills on a good game but then 0-1 deaths. I consider that to be OK. If I'm not dying I'm denying Gold.

Anyway the point I'm very slowly getting to is that it's almost always someone feeding horrendously and no matter if I'm MIAing... following the midlaner down to counter gank.... or whatever. It ends up being my fault, or the junglers, or tops, but NEVER, NEVER the fault of the person that is doing the blaming. I'm just using bot lane as an example here not singling that lane out as it happens everywhere.

What is it about people that do badly in this game and then feel the need to target others in a blatant attempt to shift blame from themselves? How can they even begin to justify it to themselves let alone other people that can I dunno... see the score and what's been happening in the game? Most importantly why is this behavior so RAMPANT in league of legends. I don't know maybe it's rampant in the real world as well, I don't get out much.

I don't know if I'm actually seeking answers here or just giving a voice to an observation that I'm consistently making.

TLDR..... Why do people who play badly always blame everyone else and never themselves?
