The real meta isn't early game meta, its a anti adc meta
The reason I say this is simple, one of the best scaling champions in league are the ADC's, and who is popular right now? Snowbally champions, and most of them happen to be good against ADC's. This is causing games to be quicker as ADC's, your main source of scaling damage is being completely shut out, while snowballing champions like Rengar, Syndra, and Annie are getting fed off of them, making the games much quicker as a result.
So, if you are a main of one of those snowballing anti adc champions, enjoy this while it lasts, I know I will, because the salt and tears of ADC's give me sustenance.
Sincerely,
A Rengar main.
