What even is this game about???

Like the other guy mentioned it's stressful and competitive. Just like most other competitive games it's got both low and high ranks. Everyone wants to get to the high ranks before quitting (or going pro haha).
I've been playing the game since season 2 and I'm only in diamond. By far my favorite game due to the challenge and individual skill that is required. ( even though it's become more of a team game over the years, sadly )
