Might & Magic: Heroes 8 - to wait or not to wait?

Reducing the number to five or six would still be acceptable, but three is completely pointless.

Well, personally, I think that creature levels are just a crutch and not needed at all. The main thing is diversity, achieved by the number of different creatures within a faction, and what levels they have is irrelevant.
And in this regard, nothing has changed in the seventh part, and an alternative for the champion level (aka the seventh tier) has even been added. Formally, everything is great. In reality, well, I've said it before, many creatures and alternatives are boringly designed, of course.
But in many ways, I agree.
