Why so many players are in DENIAL
Because alot of players believe they are playing the game correctly even when they are definitely playing it wrong. Example:
A jungler win many of his game without ganking ever because, his lane always win and carry him the victory. Even he doesn't even realize that he is being carry, he believe that he is playing correctly to carry out the victory. So when you have a jungler that does not gank, is because he clearly believe he is doing the right thing in bringing home the Victory to your screen and his.
If you for one sec tell this jungler he needs to gank cus you or whoever need help. He might tell you he doesn't have to because.....
And then you have a feeder. Let's say its your mid laner. He is 0 and 10 in lane, straight up fed his lane (obvious thing he would do like everyone else is blame the jungler)
If you try and tell him he fed his lane. He'll just straight up be an in denial that he didn't.....
I don't know if it just being in denial, but maybe it's also being dumb and stubborn
So there's absolutely no point in telling anyone in your game that there doing something wrong because they'll just think the same way back to you that you're wrong LOL
We live in a World fill with shithead people, it's better to leave it fuck, so we can move on with the next EVOLUTION QUICKER the BETTER
