I think that R&D have convinced themselves that they can get several "new" standard environments per expansion by banning stuff and shifting the meta. It seems to be settling into a pattern of:
1. New set releases, shortly after ban problematic cards from previous set while ignoring NEW problematic cards (like last year when they banned Field of the Dead right after Throne of Eldraine but ignored Oko, now with Uro but ignoring Omnath/Cobra)
2. Wait a month or so and ban SOME of the new problematic cards (Oko, probably Omnath in a month or so)
3. Repeat when next set comes out
Also the design philosophy just results in NOT FUN games of magic. If I want to play aggro and put together the best aggro deck in the format, I should be able to be an overwhelming favorite to win if I get an ideal draw. In current standard, If I'm playing RDW or Stompy, I can lose no matter when my opponent just does something insane like casts a turn 4 or 5 Ugin.
I never thought I'd say it but green has been too overpowered for too long. Ramp needs to be neutered.
