TBM - Tournaments balance mod

What does it mean that the second non-native city will be almost useless? And why only the second one? For 3 heroes on good maps, it's a normal situation when in the first few weeks you already capture several cities and start developing them (some for income, some for armies). But the situation when secondary cities match the native city in terms of race is usually not very interesting. In my opinion, it would be desirable for the cities to be of different races so as not to funnel everything into the same army and to add creativity to the army composition by mixing races. Rebuilding cities is an absolute evil in this regard. UPDATE: Actually, we are going off-topic, because I already asked a question about secondary cities in TBOM, and most players simply didn't understand why secondary cities are needed, because it changes the gameplay they are used to, where you just beat and level up endlessly. But the point of my post was that besides this strategic element, there are also others, yes, they are not very developed in Heroes 5, but why degrade them to zero, reducing the interaction between players to zero, even up to the finale.
