I'm perfectly fine with having a team that's slightly worse than me, but...
My last game was absolutely fucking ridiculous. I was jungling with Vi and bot started feeding horribly. Ok, not a big deal. I can help them. The only problem was that whenever I tried to gank them they were already dead. Ok, at least they tried, they grouped, etc.
In mid lane, we have a Vladimir whose only goal in life was to chase the enemy Leblanc ( like if it was possible to catch her if she doesn't want) and then blame the rest of us. I muted him soon so I can't tell you much about him apart from the fact that he ignored the rest of the team.
And then we have the jewel of the crown, our Garen top, who was laning vs Yasuo and decided to rush a Black Cleaver (I'm ok, it's good on him) and then mercury boots (useless vs knockups) and Sterak. Plus, the two times I was able to gank him, he decided to stay there with low hp while Yasuo had his ult available, so when i was about to kill him Garen gave him a free kill+an escape. It was only in the last 5 minutes of the games that he decided to buy some armor, wich was pointless anyways because their fed Kalista was stomping us.
Riot, why do I have to play with people who have no idea of the simple concept of what to build depending on the enemy laner? I really can't understand it.
