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

It's clear that no studio will do this.

What's that supposed to mean?
Fans can and should engage in modding, but even with the seventh installment, which seems to have good modding capabilities, what happens? If the game isn't appealing from the start, no one will create mods for it. And even if they do, no one will play them.
I suspect this is one of the reasons I haven't played the Heroes series ;)

And what's the problem? It's nonsense. Just choose the largest map size and the strongest monsters, and play for days. I've done this many times in "Heroes 5" online. They're creating a problem where there isn't one. They're coming up with all sorts of scripts...

That's true, but the balance is different on small and large maps. Although, perhaps you could ignore the balance for large maps and only balance for short online matches... But in my opinion, this would reduce the fun of offline matches, as it would limit the number of effective strategies. In "Heroes 5," all offline players play with the Necropolis, or with the Dark Elves, or with the Crystal Enclave, or a combination of these... It gets a bit boring.
