Something I discovered that certainly changes the balance of the game. I’d say it’s rather unfair and should be fixed.
You can create a outpost tower that can only be destroyed by siege for only 45 stone and fill it with tons of archers. At this point it makes the outpost tower obsolete.
What you do is build the smallest section of stone wall for 45 stone. Once you tell the villagers to begin constructing a stone wall tower, position your range units on the tower and cancel the build of the stone wall tower - you will get your 200 stone back.
Outpost tower is 100 wood, but can be attacked by units, and can only hold 5 garrisons.
With 45 stone, you can pack a ton of archers on a wall. Military units cannot attack it, and it’s inaccessible for any units on the ground to climb it.
Units are vurnerable on the wall, but also have mobility, and a faster fire rate, higher damage output than a outpost tower.
I do not consider this as a bug but rather a trick you have found to make the game easier. Similar things in starcraft would be zerg can build and cancel a BV to overdraft 1 population.
Same here, the main reason for Outposts later in the game is the high Vision radius, which this is lacking. Also leaving 10 Archers stranded in the middle of the map does not sound very intimidating.
It will become a ladder that your archers can climb. Afterwards build it again so nobody can get on top.
However you dont have to complete it, as just adding the queue order will remove the stairs.
You can also build the wall from on top of the wall, effectively being abble to build a way into your enemys base.
