Logically? The migration path makes sense. Graphic Design and User Experience are pretty easy to intertwine. The scopes are pretty adjacent.
However, we pick our migration paths based on usage statistics. In the last 90 days, there've been 23 migrations from this site to Graphic Design, of which 21% were rejected. The all-time count for migration is 68 posts over to Graphic Design, with a total rejection rate of about 12% (8 rejections, of which 4 were the 21% mentioned earlier).
So on the one hand, the frequency of migrations has picked up, being over half the previous lifetime of the site's migration rate. On the other hand, your rejection rate increased in line, being equal to the rate for the previous lifetime. And the overall numbers are still kind of low. Higher than some places, but still overall it's low. I'm not finding the numbers high enough to think that flagging for moderator attention would be insufficient or inefficient.
I'll be keeping an eye over the next 90 day cycle to see how the situation paints over that, but for now, the decision here is to not establish this path.
