DISCUSSIONS on “Rules for online games in HoMM3 and formulas for calculating player rating.”

Why can't angels be used from conservatories if the arches are built in the castle? In general, it's unlikely that everyone will agree on this, but if desired, you can simply discuss this point during a regular game.

Well, it's difficult to achieve consensus on many issues. Others need to express their opinion on this. IMHO, this will only add interest.
If you look at it from another angle, it turns out that the Fortress is removed due to its overpowered nature, but if it's not overpowered, then there's no reason to prohibit its use within the rules.
In theory, you can see both the positive and negative in any situation; it's like the question about the crocodile: is it wider or is it more likely to be green?
