"All we got from Ubisoft was Heroes 3 remake and some weird mix of stuff which is a total failure."
What we got from Ubi was an attempt to make a better game than H5, which they absolutely did. If you didn't like H5 (and I would empathize with you), then you're beef is more with Ubi and not H6 itself. But if not, I have to disagree with you completely.
You don't to take my word for it either. Game reviewers of all kinds admitted that H6 is the most refreshing, immersive, and genuine Heroes game we've gotten in a while.
Areas of control were implemented to force conflict by prioritizing conquest (which is what the game is about) and end resource wars.
Rare resources were combined into a single rare resource that all factions can use. Since every faction in every Heroes game ever primarily used a specific rare resource to fuel its economy, making a single resource that each faction can use equally well has zero negative impact on gameplay and just makes acquiring resources less tedious in general.
Although I preferred H5's skill system (the only thing the game had going for it honestly), the H6 skill system uses trees. Not groundbreaking, but not broken either. There are several pros and cons to the skill tree system the way they implemented it, but the bottom line is that it works, and its something different from past games as well.
Then of course there is the fact that the game has better, more realistic graphics AND music.
If you're going to play the "Broken Online Interface" card, not only is that not part of the game, but I doubt the issues were Black Hole's fault to begin with.
