Generally, it depends on how you look at upgrading magic creatures. On one hand, you get all the benefits that come with the upgrade, but on the other hand, you lose the ability to cast spells on them. In any case, if upgrading is allowed, perhaps after building a magic school or gathering resources, it would be more interesting than playing the way it is now.

In HotA, it's clearly Conflux, no questions about it ;).

In HoMM it is definitely Conflux, no questions asked ;).

Yeah, sure =D fakes that you can't reach in the first week (and after the first week, what's the point of them...), birds that are more expensive and even weaker, and fewer in number too. With such odds, what are you supposed to fight with there?)) A dozen fish and air elementals?) Yeah, sure, there are birds in Tower (but what do you take them out with?), you can upgrade them, etc., but more often than not, if the template isn't rich, you'll have to wait until the third week for the next growth and at least some kind of decent meat.

No, it's just that this is the only game objective that actually forces you to spend 2-4 extra days searching for something (flying around to resurrect, killing others), and at most makes it impossible to complete – it's been a long time coming to fix this!

You just want to breeze through everything for free :D
