Heroes 5.5 WarGame Edition - Tactical Edition.

In the new schemes, there is no need to discard buildings, as there is no shortage of space. Regarding fortifications, I have come to the conclusion that they should not accelerate upgrades, as they already work very well (by increasing the growth rate). Upgrades will provide a fixed, one-time bonus equal to twice the base growth rate, except for tier 7 (where it will be a single bonus). There is the possibility of returning buildings like farms with a similar bonus to upgrading (+200%), but not as a one-time bonus, but weekly (to the growth rate). For example, militia farms +16 militia per week. They can be placed as an additional improvement, after the upgrade (in the same slot).
