I agree. Be honest in your feedback back to them. I myself like the idea, but not the implementation, and I wouldn’t want to just “fudge” things and end up with a system that in the end I don’t use because its half-baked.
If this UA doesn’t end up in the 2024 PHB or DMG, they may take a stab at it in a book of its own later down the line with revisions based on the detailed comments, giving us a much better product. If they never touch it again, we still have the UA and the community can iterate on it anyways.
