Why is Riot focusing on Chromas and making the game more complicated rather than making the game more fun?

I think I might be the only one thinking this, but I want to know if other people agree with me.

So far we are flooded with Chromas, complex new champions (several), an even more rapid changing meta and weird story line events.

Why not : -keep the game simple? -Release more simple champs like Thresh. -Nerf crazy champs like Ekko. Reduce the OPness of items and keep the game nice and slow.

Because at the end of the day, it is less stressful and more fun that way :)
