Why is League going through consistent downgrading? *in design*

A few PNG icons called Mastery points are still not finished. Also previous ranked divisions looked way more interesting. They are just icons but why? Why are they changed from something that is objectively better suited for what it's for? It just keeps happening over and over again. Client re-designs, ranked divisions, hextech loot, mastery points, summoner spells... Let's guess what might be next? Just how exactly does a company of this size keep ignoring that broken and underoptimized client from which you start playing the actual game? Year after year I expect a proper announcment for a complete re-design of these things, but I've been on copium this whole time???

I highly suggest to look back and compare some of these re-designs.
