Riot is making the same mistake as blizzard.
Blizzard undervalued the casual player, balanced SC2 purely around esports and completely ignoring the start up experience for new players, in a game with an obscenely steep learning curve.
Why the casual player? (also warning, very narrow stereotyping ahead)
Well, remove every pro and challenger player, the smallest player population in league of legends.
Now remove the hardcore, balls to the walls players, league of legends is the only game they play. Players who, regardless of rank are in ultra try hard mode, trying to improve and rank up, likely playing 4-8 games after school/work or 15+ if they have no life.
Now remember, having a diamond/platinum rank doesn't mean they try hard, they may just be good casual players who like having bans, or the intensity of ranked.
This group is the second largest population, they'll likely stick with league regardless of the meta/balance
Now the final, the casual gamer. They likely play for fun, because lol is a FTP game that anyone can get (social) or to spice up their gaming line up.
This is riot's largest base and the one they will suffer the most from if it disappears.
The casual player base:
- fuels the esport scene (surprisingly more than the HC players, who play rather than watch)
- are a huge source of Riot's income
- make up the majority, and as such are who're responsible for your queue times
- and have other games to play, if LOL turns to shit, they dgaf as they can just move on to the next game.
By losing their casual players, SC2 lost their esports scene, which is now a pathetic couple of twitch channels that re broadcast games from years ago, a dead set of team queues, custom queues and forums. They lost sponsors, (they're fken relying on the community for this years global championships)
And from their, some hardcore players left as well.
This will happen to league if riot doesn't get the head out of their asses and make esports the last thing on their to do list.
