Here's why League sucks right now, in my eyes at least.
One person can't win you the game, but one person can lose you the game. It's so fucking hard to carry yourself through games where you have a 3/21 bot lane now, games snowball way to hard, and even if you are solo carrying, the enemy has so many flexible options of throwing your hard work in the trash (Rift, elemental dragons, etc). Before all this was introduced, you could easily win games with afks and int feeders, now it seems impossible
That's just me though.
