Yeah. I knew a few people who moved to Dynamis because they could always DC travel and get to places on Crystal. With these silly restrictions, they are mostly all planning on moving back to Crystal ASAP.
Personally, I wouldn't move to Dynamis even if SE reverts the change at this point. There will always be a chance in the future they do this again or implement some other poorly thought out idea and you're stuck again until however long it takes them to care. They're very quick to implement stuff like this, but it'll take them half a year or more to revert it. This is assuming they aren't stubborn about it and simply refuse to change it back.
Thinking about it: Housing is at the root of a lot of the problems with server populations. Since they're so difficult to get, no one with a house is ever going to want to move. This also means a lot of older, popular hangout spots are in those original servers too. Even people without houses will want to go the original server if it's a spot they link to hangout at, rp, whatever.
The server populations will never spread out until SE adds instanced housing, which would move with you to new servers. But it's been like a decade and they haven't cared to do anything meaningful about that, so I doubt it's happening. This game just does everything possible to make it really hard to play with friends sometimes.
