This snowball meta is ridiculous. Practically every game feels completely one-sided. A single kill, or gank can completely destroy any laner. Once ahead, masteries make trades even more punishing and with towers being paper thin, the game is often decided before 15 minutes. Having small mistakes be so punishable has made ranked a less competitive experience, especially in low elo.
Adding all of that to the amount of champions that can abuse masteries, all of the balance issues... Honestly masteries need to be reverted and changed so that they don't create so many balance issues. Balancing champions around which mastery is best on them is stupid.
