Well, maybe they are absent because of a monopoly? Think about it yourself: for example, how can I compete with 5.5 if everything I do is automatically dragged into 5.5 anyway?
Regarding the combination of different exes, I have nothing bad to say. But could you explain in a few words specifically how 5.5 increases the moddability of the game? I admit I'm not very familiar with the functionality of 5.5, but I suspect it's just another behemoth with a huge amount of everything all at once, thrown into one pile. For instance, Eva honestly repulses me because "twenty recolored minotaurs" is exactly my sore spot. In general, I've always been more for quality than quantity.

I already said that I'm not for WoG, but for HotA.
I'm simply not interested in a project consisting of 90 percent of a large amount of motley trash piled into one heap. I would rather see, or create, a neat, high-quality project made with attention to detail, even if it is significantly smaller. But alas, in the current climate, this is simply impossible. Any potential HotA now will be brazenly swallowed in its infancy by your WoG analog, i.e., 5.5.
That's exactly why I say those guys are creating a monopoly.
And honestly, I never cease to be amazed by the indifference of our small community.
Large groups and streamers publish mods without links or authorship? Who cares, why bother writing anything.
They steal large well-known mods—everything that isn't nailed down—thereby preventing small projects from gaining an audience. Who cares.
Let's create our own resources to develop? No, that's not necessary.
I'm starting to give up because of such a reaction. Am I really the only one who cares about all this?
Moreover, sometimes such things are even praised.
Groups that stole resources without citing authorship—that's good, a good replacement for dead sites.
5.5 is good, it's WoG. For heaven's sake, look around; this attitude has led to the fact that there is nothing left except 5.5.
At the same time, it's not hard at all to do things differently. 5.5 could publish links to the mods it uses and create optional compatibility patches. Groups and streamers—as already proven by Remix and the admin of this group—can publish mods with links to the authors.
This is important. It's important that people who like mods for 5 know that our site exists and that we are here. And that modding Heroes does not end exclusively with Dreadnaut and his 5.5 mod. Why am I explaining obvious things again? And how can I make it so you don't give a damn about the development of our community?
I agree with you 95% (the 5% is due to my dislike of WoG
); I don't see anything bad in 5.5, on the contrary—it's a kind of framework upon which additions\improvements can be attached, and one can view 5.5 as something that promotes the spread of our Creation... I'll even give a real-life example: Bill Gates was once asked why his company doesn't fight software pirates... to which he replied: my dream is to see our software on as many computers as possible! ;)
