Non-cosmetic DLCs are for players who played the original game, liked it, LEARNED IT and want more. Similarly, it would be wrong for a casual to skip Native and play a big complex mod full of new mechanics. It will look obnoxiously overdone, when in reality it's feature-rich if you are an experienced player and that's just what you need after Native."not worth it. mods do this already and better. the new features are mostly obnoxiously overdone as well." doesn't sound like a tech support issue to me.
Like, if you think the average Steam user is some casual player who only wants a bit of swordplay and an overmap to run around on? Sure, I agree. If you want to go further and say that they also don't recognize quality games, you lost me there, but it is at least understandable. But WB blew it out of the water with not even a quarter of the features, even accounting for the terrible release.
That's why I think the new player experience (i.e. someone who doesn't know a damned thing, just picking it up and playing casually) is more important than complexity or depth.
