For example: why does a Fortress cost 5000 when it doesn't increase the army size and only adds a wall? A Stronghold costs the same, but it adds an army and a moat with a tower.
The only + is that upgrading level 7 creatures is now cheaper compared to Heroes 3.
I would like to see more "minuses" like those in Heroes 5 compared to Heroes 3 in HoMM 6.
