[2021] In a Q&A, Riot confirmed they want the game to be short, high length instakill fests, because it caters to Chinese players.

The representation in the video is not exactly accurate. We did say that certain regions have certain preferences (this doesn't just mean China for example) regarding damage and that we have a lot of discussions internally about it. In that meeting, we did NOT say that damage in league is staying the way it is ad infinitum, nor that we are happy or unhappy with where it is currently.

Regardless of whether a region likes damage a certain way, if we determined it was worth changing the amount of damage for some reasons (whether that's increasing the quality of tactical gameplay, slowing down combat, etc.), then there's a possibility that it will still be done.

Notably, there are a lot of flow on effects from changing damage that require weeks, if not months of follow up work and instability, including completely up ending the meta and game understanding for Pro play, so that's also one of the considerations. It would not be as simple as just reducing damage by X% and the game is fixed. Tanks, assassins, adc, sustain, pro play watchability, game snowballiness are just some of the places that would likely need adjustment.

I know you're not going to believe me, but revenue is not even remotely a consideration for people making gameplay changes and I've been on the team since season 4, including the live gameplay era. Sometimes skins come out and I didn't even know they were in development, so I wouldn't agree with this take at all.
