Yeah, many people seem to have gotten the idea that UA is crowdsourced game design. It very much isn't. Other people think it's an open playtest. It isn't that either. What it is, is a popularity poll. It asks, "Do you like this? Are we going in the right direction? Or do these design choices make you unhappy?"It's usually not about the specific mechanics with lineage playtests in UA, and more about "is this flavour on target?"
They have internal playtesters to let them know if the mechanics are working right. What they needed to gleam from the larger community is if people were on-board with Goblinoids becoming fey. The answer seemed to be an emphatic yes.
That's why when WotC talks about UA they talk about approval percentages. Lots of positive responses means they know they're hitting the right notes with at least a substantive majority of players. Low marks means an idea will be revised or discarded. They're using the bait of early access to gather customer data, and at an early enough stage to make changes before final release.
