Change to Poles Villager regeneration bonus

Since the new PUP introduce the concept of “healing area” with the new Celts UT, wouldn’t be fair to apply it to the Poles’ Villager regeneration bonus?
Instead of nerfing it directly in the Dark Age, the bonus could be bound to the proximity of a Folwark and/or Town Center. This way it would be pretty defensive and couldn’t be abused by forward vills.
