Am I pleased that WotC is actually reading DMsG products and featuring them? Yes.
Am I pleased with the notion that we're losing half of the new playtest mechanics distributed in a year because of this? Not in the slightest.
Having new semi-official mechanics to look at each month was the reason that I enjoyed reading UA articles. It showed that further development of 5e materials was continuing each month. It gave some insight into what was coming down the pipe. It sparked conversations about what was done right and what was broken beyond belief. Those conversations would then be reflected by our responses to the followup surveys, which would then influence further UA articles. It was a contiguous loop of development and feedback.
Now we're left with six months of UA articles being devoted to stuff that many people here won't be bothered to read, because of the low likelihood of any of it becoming official material. This should have been made a separate series of articles from the get go. I plan on saying such when the next survey comes out.
If this is truly the future of UA, then I'm not going to bother checking it on odd-numbered months anymore. They will only get my clicks in February, April, June, August, October, and December.
