0. Literally.
The community get's talked a lot, but the developers and the game design are utter garbage. I played back in season 4 and 5 and was quite highly ranked. And I remember the day Riot hired the Blizzard dev to run the game. Some guy who almost ruined Wow. A few people sounded the alarm then, and what happened since was. . . absolutely horrendous.
Basically, Lol transformed into this weird Frankenstein's monster of spread sheets and people who hate video games. The developers don't like the game and they have no concept of what fun is. Everything is just numbers on a spread sheet. There's this weird abortion of a philosophy where if the game is balanced, it's a good game.
Rock paper scissors is balanced, it's not a good game.
The game designers are almost run by the marketing team to the point where I don't think even care about the game itself. Everything is about E-sports. Release new champions that can make big plays; "five second clips on youtube and twitter are how we're popular." Any concept of longevity and fun and real balance are out the window. As long as you can create the veneer of popularity, you have a marketable product.
And the funny thing is, is that it has worked to some degree. The player base is down and the game is a pariah, but it still exists and makes money on that prestige of being Lol. It would have been easier just to make a game people wanted to play, but their cynical mass marketing, "play us because we're popular" corporatism has worked.
Games have this weird quality where you need a lot of people to attract people, so it's in that weird self sustaining phase where people put up with it, but I don't think there are many people who genuinely like, let alone love, Lol.
, I just need good positioning and spamming of heal.
