Heroes 5.5 WarGame Edition - Tactical Edition.

You don't seem to consider that you spend a whole 3 days out of the first week on fully building up the Castle. This means that both the first and second weeks will suffer in terms of troop production.

Moreover, the Castle is useless during the first week. In WGE, building up to the Castle will cost 1000 (Town Hall) + 3000 (Magistrate) + 6000 (Castle). This means that the Castle will only pay for itself 3 days after construction.

I agree, but I would make the cost of the Town Hall 1500 so that, like the Magistrate and the Castle, it would only pay for itself on the 3rd day ((1000-500)/1500=3).

I repeat: I really liked your 5x5 building scheme (the last one with the Dungeon) with a full line of Town Hall - Magistrate - Castle (3-5-7)!
I think it can be taken as the main one.

P.S. I see that you have removed buildings that provide a small increase and buildings with a small bonus from your schemes. Which is basically correct; 2 racial buildings (Stables and Training Grounds or Altar of Elements and Trading Guild) per Castle is perfectly fine.
