Kostya, the one who has to rebuild their Guild more often will lose in the long run. Also, there's critical morale, which can lead to a loss after losing momentum. And you also need to guess which Castle to build your Grand Mage in.
And the phrase about having to guess where to build only reinforces the idea that, for you, Heroes is a guessing game...
And morale isn't even a point of contention. Morale exists in HotA, but rebuilding doesn't exist in SoD.
You can play both versions, and as practice shows, people play and will continue to play the SoD as it is now, and that's perhaps the most important thing, and it's also improving in terms of comfort thanks to the MOD!
