Small supportive community.
Long term progression vs short term progression clearly visible
Community just straight out targets every person that is offensive.
Lack of dev communication (however, they do take suggestions)
Pay to win at early levels, free to play and free to win long term.
Community is stable due to game genre.
League of legends
Huge, but rather unsupportive and destructive community.
Free to play, you don't need to buy anything to win the game(or a match) short or long term.
Community targets everybody, even those who have done nothing wrong
Highly communicative dev team on one server, lack of communication on other(no specifics, due to nature of community)
Community is unstable: can have huge increase and drop in the same year or stay stable for years.
So...hmm...maybe esports is the problem of league? While it allows league to be totally free to play, it also causes community to think league has to be exactly the same on all levels of play.
