You expect everyone to take ranked seriously when games like these are most common?
Take note, games like that are normal for me. The only time I go negative is when I give up and quit trying, and it's for the same reason: I see another one of these crappy, frustrating, infuriating and unfair losses at the end of the tunnel. It just isn't worth it.
Tell me it's fair to have me set kills up perfectly and for Vayne to turn her back on them and forget to take my advice to build Guinsoo+BotRK, even if she was fairly decent. Tell me it's fair to have a jungler who openly admits to being drunk, who ignores advice, teamfights and all of that 'good stuff.'
Seriously, this game used to be fun. It used to be legitimately fun, in S6 and near the center of S7. I was here when Yasuo was released, and I was still having fun when his wind-wall lasted five seconds and he blocked absolutely everything thrown at him. I felt like I really impacted a game, and I felt that -- even as a support -- I could carry hard enough to win.
What, Riot, you want me to give up and start trolling Ranked play because it's more fun than taking it seriously? I'm happy to, because, guess what... I'd enjoy that a lot more than this. You've noticed a distinct plethora of trolls and feeders, right? Maybe it's because your game isn't worth playing anymore.
What's worse, I'm now afraid to play another game because I might get more people exactly like that... and then I get demoted and there goes all of my hard work. So I guess I won't play another. I'll let the last ranked match I've played speak for itself.
