Sorry for the rant. Tl;dr: smurfs are bad, but the frequency of them invalidates the climb.
I don't know if I'm just unlucky, but I think about 85-90% of my games have at least one smurf in them. I don't want to win because a Master ADC 1v9s. And I certainly don't want to lose because my opponent is a 95% winrate Asol smurf.
I think my biggest gripe is the frequency, though. I don't mind the odd game, but the fact that its a nice surprise to get a fair, balanced game is a disgrace. Again, sorry for the rant but I just feel like my rank doesn't even matter anymore because my daily climb/fall is just an RNG of if the smurf gods were smiling on me.
