Why people play LOL?

Im playing since 4 or 5 years now. Its basicly the game in which ive got the most playtime on by far. Its funny yes, but u cant ignore the fact that there are just too many flamers in league. Its getting better as u improve cuz u cant improve without being chilled and stop flaming xD i personally reached gold just a few weeks ago and sometimes its hard and it can ruin your day but sometimes it saves your day aswell
