I Get what Riot is trying to do with rank
And I have to say it really not bad at all. Think about it. Whenever you ask someone about why they can't climb they always say " TEAM IS TRASH GG CAN"T CARRY" Well now you can have a whole team in rank so if you guys still lose maybe you not as good as you think you are. I already know what people are gonna say so let me just answer the questions in a short list.
"What if I don't wanna play with others" Ok that's cool but don't cry and complain about trolls, flamers, and afkers because if you're playing with people you know for a fact that's not gonna troll then it makes the game a whole lot easier. I don't know how most people play but I don't care how good you are, If you're toxic I'm not playing with you. After all League is a team base game so I'd want people I can trust to play with but if you like playing alone that's fine.
" What if I'm matched with a +4 or +3 team and they troll" If all it takes is one person to ruin a game then having 4 or 3 people do it is not gonna be any different.
"What If I can't find a team" So you're telling me you don't have a single friend in this game out of the MILLIONS of people who play. If you really don't then as you play you're gonna meet them. Good people will want to play with good people so IF YOU"RE AS GOOD AS YOU THINK YOU ARE THEN THIS WILL NOT BE A PROBLEM.
The only real problem is Smurfing. Riot is trying to kill the whole toxic,troll dilemma with pushing you to find a team and it's a good ideal.
