Role playing is fun, not kidding, it really is.

So you quit because you played bad?
You are stupid.
Go play again! You can't possibly grasp the game well in your first games, it's impossible, this isn't a fps game or anything like that, it's different.
Just keep playing. It's like math, if you don't practice it you'll never be good at it.
Yes, this also applies in MOBAs.
I never played DOTA 2, well, I did once, so I don't know how bad/good it is, but LoL isn't as bad as people make out because, most of the times, the bad people are the ones complaining instead of playing.
I was with a friend. It still sucked. Being bad means that games aren't fun, and when games aren't fun, they suck, and when games suck, Decagon stops playing them.
Math has never been like that, you either get it and you'll do fine, or you'll never get it and you'll fail. Seems to be this way as well in LoL.
