Do you ship Land grab or Advanced rice paddy?

Land grab reduces the cost for mill, plantation and livestock pen by 40% and they are built in a quarter of a regular building time. This gives you mill for 240 wood, plantation for 480 wood and pen for 120 wood. Advanced rice paddy gives you, well, a rice paddy for 200 wood instead of 400, and provides some extra HPs to a paddy.

I've noticed not many players use it, althrough it saves a great amount of wood. For example, around 23 minutes of game all hunts and mines are gone, you have to build 3 mills and 3 plantations and that costs you 3600 wood without land grab or 2160 with land grab (you save 1440 wood).

Do you use it? And why not?
