Do you really think there's a difference between servers ?

I mean the quality of players and rank. Because I'm diamond 2 on eune right now and there's that doubt in my mind that I'm not actually good, from all those years of people talking shit about servers that aren't NA or EUW. Obviously, I'd say challenger rank is different, because all pro players go on EUW, but other than that, I think it should be the same. People are... people everywhere right, only thing I can think of is that on more populated serves, you'd need to play more games to reach your rank because there's more people playing = more bad players and you need to swim through all that trash longer hehe xd. I played 5 games on my friends acc on EUW and given it was a silver account, but those games were one of the worst games I played in league. People farming top while the enemy is killing our base, french duo "doesn't care about this game hehe xd" and shit like that. So of course there's trolls and feeders everywhere, and that's why I don't understand when people say "oh lul eune so shit".
