Heroes 5.5 WarGame Edition - Tactical Edition.

Well, we won't tie upgrades to forts anymore, meaning they will be fixed, right? The question is, if the influx is the same as from the base, then the upgrade gives too few bonuses, because, unlike the base, it doesn't provide a weekly increase.

Excessive (but this is not certain) total amount of resources, weaker performance, for example, a stack of 1 dragon, 1 titan, etc.
Difference between option 1 and option 2: x2, x4, x2 (by item). It is possible to make it x2, x2, x2 or leave it as is (if there is a need to strengthen the bonus from upgrades - think further)
...
P.S.: yes, I forgot a little about the equality of the base - upgrade - alt-upgrade. In general, it is an interesting concept of '1 unit also a stack' and I would still like to see it in the mod. (if it is still relevant)
...
Upgrade and alt-upgrade provide an additional weekly increase. In the game conditions, 1-2 weeks is a good immediate bonus to strengthen a specific stack.
Is it really necessary to further strengthen it?
