Forfeiting are Exploding since Runes/Masteries
More than half of my games end with forfeits now, with most of them being a full team early quit between 15-20 minutes.
Bottom laners can easily get 2-3 kills on their ADC by the 3-6 minute mark without trying based of the new runes/mysteries.
You cannot stop any high burst champ that starts 3/0 or 4/0 currently if it happens to get that way before 10 minutes. Which is just about one person is every game. So if you give up 3 kills early people are just leaving their lane as they only become food and their entire team is raging at them for simply picking the wrong runes/champ.
All Meta has been thrown out the window. Janna ADC is currently working......... She has impaired movement (+ dmg) and increased damage with her own shield. You give her another champ with impaired or stuns (+ dmg), she can run over bot lane.
Worst lane that I've seen since the updated was a Morg /Jhin bottom. It was already crazy strong before if you could combo the stuns, which isn't hard t do. Now either one starts the stun train, it's a kill. This is almost a guaranteed forfeit lane if the other team picks a melee support or short ranged adc.
