Stone wall change against castle drop

Continuing the discussion from Increase building time for castle drop:

  • “Stone walls can protect buildings and units within 3 tiles from castle arrows (not other attacks)”

Will that change be good for castle drop counter? I think it will be better than increasing building castle time.

Not sure how it can be implemented. Currently, there is no generic tech in siege workshop. Maybe we can have one to allow more swordsmen to garrison inside rams. It is reasonable that rams have less space for polearms…
