HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

But now this option is not available in any form. And this is already a significant reason to abandon HD+ in tournaments, for example, in the current M200, where the game relies heavily on randomness and has many neutral villages (and now there will be no second-level troops there), as well as in Anarchy and other scenarios. Here, a fixed second-level building has been proposed (imposed) without the possibility of changing it. The author's motives are interesting. Or, most likely, this is just a hasty addition.

It's simply easier to add functionality than functionality + an option.
What appeared in 3.26 is not the final version.
I don't see anything terrible in this addition.
Moreover, how is it worse than, say, the 2-6 level creatures in refugee camps, or the absence of the quick battle bug, which exists in HD+?
In my opinion, it's much less terrible.
In general, I find it very funny on this forum lately.
I read every few posts: "Make the second-level building available, just do it!", and then, "Oh, what a nightmare, why did you do this!", it's ridiculous.

for example, in the current M200, where the game relies heavily on randomness and has many neutral villages (and now there will be no second-level troops there), as well as in Anarchy and other scenarios.

And? Will it be impossible to play?
I didn't expect HD+ to be allowed in pure SoD tournaments anyway, because it's already a slightly different game, and without changes to the initial city building.
