It's a shame that Google doesn't give you the ability to give less than 1 star as I would love to have given it less. I've seen comments describing the game as "difficult to learn" when you're new. This is false. You can't learn the game if you are new - the sweaty pre-teens and middle-aged adult men who grind for hundreds of hours, have made it impossible to learn the game beyond the tutorial.
The seemingly endless amount of chromosome deficient males from 11-45 has made the community somewhat of a gem. You won't find the mute button more of an asset to any other game than for league. Normally, what you'd expect from a team game is co-operation, fun, and TEAMWORK. Though for this game, think differently, think like a caveman - because that's what you'll get beyond maybe a win or two here and there.
This game is not fun
It's not entertaining
It's also not challenging as that would imply there is a goal to be achieved, there isn't.
Don't get this game, use your disk space for something else.
PS. plenty of racism, homophobia and general disgusting people
