I find it odd that when you defeat a tower there is no additional benefit to the winner other than in any battle. Sure, the enemy loses territory, but that is it.
It’s make more sense to leave the tower standing and in the Victor’s hands. This would make defending a tower much more vital so more troops would stay close, and would help Victor’s extend territory. As it is now you have to have stones and a worker available plus wait out the build time to take the territory.
The newly acquired tower could be weaker for a time, perhaps, and need to be upgraded to get to full strength. That would allow for some fun strategic back and forth. It would also make quick reversal of Fortune possible, whereas right now the Conquest is pretty much determined halfway through.
