It will not only make the experience better for everyone you play with. But if you figure out what you could have done different to improve your chances of winning after every loss, you will improve dramatically faster as a player. In both aspects of teamwork and playing the game.
So keep your head up and focus on improving every game! Good luck on the rift summoners!
It's best not to assign blame at all actually. Blame is just a way of scapegoating problems. It doesn't do anything towards solving problems.
But the premade of 4 ragequit. What do.
I hate when people blame me for not mia, lik rly? Put some wards down and pay attention to your map, its not my fault!
Some times it is really hard to do that, for example in my last game it was basically a 3v7 with my bot lane feeding non stop at a rate of about 2.5 minute/death. Especially when they rushed death cap on karma support and qss on draven.
So i got an afker in team, what i did wrong?
I'm going to blame myself because I have an ashe bot on my team who tower dives and only has 
at 30 minutes as full support 
.
[spoiler alert, that just happened]
Go be stupid somewhere else.
In a lot of my losses, I do well in laning phase, often shoving out my opponent from CS. My losses often come from the other lanes being lost and a snowball from there ends up winning them the game.
Do you think I should roam more? If I can screw over other lanes it would give my team a chance to snowball on more lanes right?
Good philosophy, but all games aren't winnable.
