Nah the DMG told you how to adjudicate on the fly.
The complexity came from the later options bloat.
The same WOTC that got mad that 3PP did that exact thing and they attempted to control the whole market by funneling all 3PP through them?
That WOTC?
Also the WotC that listened to feedback, changed directions and now supports 3PP in DDB.
You can't have third parties through the parts that you don't want to do then be upset that you don't get a cut out of it.
I don't even know what you're trying to say. There's plenty of 3PP, it's not going anywhere and in many ways WotC is actively supporting it.
