I'm talking about continuity.
There are indeed many new features, giving hardcore players more room to explore. So, in terms of both continuity and development, it's all good.
But in terms of plot and design, it's a patchwork quilt. There are many borrowings from everywhere. Given the vast wealth of original concepts in the Might and Magic world, these borrowings are justified only by the "popularization" that increases the audience and sales of Heroes V.

Firstly, the graphics have become more "cartoonish" to attract children and be more similar to the second game.
Secondly, the fifth game is a high-quality commercial product because no one wants to repeat the fate of someone – remember who – who sold their rights later! If you want to survive, you need to adapt.
Thirdly, what do YOU mean by "popularization"? Could you be more specific, because I personally don't understand?

I personally associate the fifth game with Warcraft 3. That's why I miss the super-bright cutscenes in the intermissions between campaigns.

P.S. I understand that you're not happy with the plot? What would YOU CONCRETELY change in the storyline?
P.P.S. I really miss scenario maps, but I understand that it didn't take just one night to create the maps for the third game (after all, the game is 10 years old)
