Sorties from >5 000 forts

[Wizzington]

Garrisons are 1k * fort level. 5k did not work balance wise. You need 3k troops to besiege 1k garrison though.

They do not use manpower, but local manpower of province has a big impact on garrison reinforce rate.

The first fort building gives +2 fort levels. What do the next 3 fort buildings give? 3, 4, 5 or 4, 6, 8?

There are 4 forts which each give +2 levels.
