i hate rank

swear every match is the same... me doing my lane, doing best as usual, bot feeding, jungle getting fed etc etc etc... and at the end of the match I wonde rwhy im losing 25lp and only winning 15. Just getting really fed up with this game. Tired of spending 30 mins of my time just to lose cause my team can't play properly. I just don't know anymore, i play my role properly, i ward, i try to stay postiive, encourage team now, but just... sigh.
