Heroes 5.5 WarGame Edition - Tactical Edition.

When heroes meet, part of the turn is lost, but when leaving/taking a garrison, it is not.

Perhaps simply track whether the troops in the garrison have been rearranged or not? Or introduce garrisons with the option of not taking troops out of them (in campaigns they are almost always used, it can also be done in multiplayer).

But it is not yet clear how it affects the gameplay as a whole, whether such a strategy adds interest, or it is just an unnecessary complication.

It adds delays, which is not very good due to the concept of the mod.
