Walkthroughs for custom maps.

Seriously, facepalm. Where were you 10-15 years ago when there were awesome offline Tournaments with map Walkthroughs for speed, which were held here and on HeroeSports. People didn't engage in this kind of nonsense; there was real skill!

About 12-13 years ago, I was in the top three and even won offline Tournaments, although on a different site - HeroLeague. But back then, there were no signs of a unified Heroes community site. And I don't share this concept of "the grass was greener back then." Rather, the opposite is true; the set of tricks and techniques, both related to bugs and not, has grown significantly. At a minimum, this is reflected in the physics engine, which has grown significantly in content and in the number of people who use it over the past 10 years. And the level of maps has grown... but if you don't play them, how will you see it? What appeared 10-15 years ago from hardcore maps that comes to mind is only Xiedu - and even then, few people completed it, but now there's The Last Crusade, Metataxer's Revenge, a bunch of Chinese maps, puzzle maps from RoseKavalier, Obi, wenwell - all of them appeared after 2010.
And even in online games, there's a sharp increase in quality and skill. The champions have changed - before, you could admire Maretti and ATG, but now they're not dominating everyone. Except perhaps Stinger and Bishop, who have consistently been strong, probably since the time of the dinosaurs), but their level has also increased.
In short, it's not worth dwelling on the past and drawing conclusions based on examples taken out of context.
