But he did manage it, didn't he? He figured it out? He analyzed the game mechanics, identified the weak points, and, like a master swordsman, struck them right in the heart? Is he still a "redneck" after that?

If he was the first to do it, then maybe you're right. But a normal person would say, "What are these balance issues, gentlemen?" Many people said something similar after patch 1.6 for LoR.

And how is this different from endlessly grinding Inquisitor Phantoms or something?

At least in the second case, you have to at least make sure you don't get wiped out before you wipe them out (otherwise, there will be no one to "grind" with). In the first case, it's impossible to lose because the computer doesn't deal any damage.

So, you read the plot on the wiki before going to the cinema, and then you can decide whether or not to go to the cinema with a clear conscience?

Something like that. :D

And how does this manifest itself? We have Alexiglu, who is 15 years old, and you claim that completing this mod will be an absolutely impossible task for him?

Well, why not? I think he'll manage it on easy, just like all the other players in the 1st and 2nd categories. And even casual players will cope, although maybe they'll have to turn off auto-battle for that.
But as for the "impossible" difficulty, I don't know... I personally struggled to complete it.

But it didn't sell well – so, "rednecks" aren't involved here, because they didn't start voting with their wallets for garbage instead of a game, right?

I don't have access to sales statistics to draw any conclusions. But maybe they went too far with the "careless attitude."
The problems in the starting battles in "Warlords" didn't bother the "rednecks" because, due to the losses in those battles, they didn't see the coveted zero in the "your losses" column.
But normal players were unhappy with what happened after those battles (you come, you see, you kill everyone).
In "Dark Sides," as far as I know, the same thing happened.
