Reven, I don't really want to talk about HotA. I will speak when it is released, when I evaluate the novelty it brings to the game, and when I see what work was done specifically by the HotA team, rather than what they borrowed from other people and presented as their own achievements. I am without a doubt sure that some of the graphics in their addon will be at a high level, but as for the technical side, it seems to me (perhaps I am wrong) that it will not be far off from VOG 3.58. On top of everything else, I am certain that the addon will be full of errors, glitches, and bugs — it is simply impossible to catch all of that in such a short period.
Secondly, same-day Gorynych will be present in the town, but not as a regular unit, rather as a Town Defender once the Grail is built in the town. That is, if the Alatyr Stone (that's what the grail will be called) is built in the Kremlin, then during a siege of the town, several Gorynychs will appear in the garrison (we are still discussing the number; perhaps it will depend on the current month, for example 2 gorynychs for each month of gameplay).
Reven, and why didn't you like Baba Yaga? In my opinion, she is the most colorful character of Russian fairy tales; as far as I remember, their presence in the town was not even contested by anyone.
I agree that Kot Bayun hasn't been finalized yet — maybe that's why he didn't make an impression, but I think there aren't many feline creatures in Heroes — which is why we settled on the Big Cat. Or did you not like his stats?
