Just as treant form is not mandatory anymore, so should moonkin form lay down. Sure it can stay as a cosmetic shapeshift, but the increase in effectiveness should be baseline for all Balance druids.
Druid should have at least an option whether they want to run around as a fat cosmic chicken or not, Balance could be much more enjoyable this way and you would finally actually see how your character improves by getting new armor. The main reason I started an Elemental Shaman and not a druid back then was because of this hideous shapeshift requirement.
A druid can't even use transmog options properly because they are forced to remain shapeshifted most of the time.
