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

What will be the difference between "Isro and Vidomina attacking heroes, cities, and mines with a garrison of the opponent using expert spellcasting" and "Isro and Vidomina attacking heroes, cities, and mines with a garrison of the opponent using non-expert spellcasting"? When it comes to neutral creatures, everything is clear, and you can even dismiss all the skeletons raised with their help. But why is it different here? Sometimes, Isro and Vidomina will be at the end of the chain (or released from prison – and it doesn't matter which hero is in prison, even if it's Sraka – the mere presence of a hero is what matters), and they need to take or attack something. But it turns out that in some situations, I will be simply restricted by the rules, even though I could attack the opponent and win. In my opinion, it's some kind of nonsense...
