Which castle is the most difficult?

I reread the correspondence. I'm still glad that Heroes is alive and kicking, and people are actively playing it. I'm glad that we're having these last warm days. I'm in a good mood, even though few people care, and this is all off-topic. We're all chatting about things that aren't really related anyway. We're here teaching a naive newbie how to play properly. Everyone now understands that I'm one of those players who likes to take their time and play on an interesting map against the AI. And the latest user-created campaign, "Return," was simply amazing. And yes, I made a mage with all the schools, wisdom, intelligence, archery, and magic (it was like that from the beginning). With 2k mana and almost all the spells (except for flight and teleport, which were forbidden), primary stats at 99, and a vulnerability aura, I didn't care that I didn't have logistics (no gloves or boots), that my opponent had expert attack and defense, tactics, and resistance... Cloned snipers, buffed with prayer, accuracy, and blessing, were shooting down slowed, blinded, and blasted hydras, titans, archons, and black dragons, while firebirds stood modestly aside, giving the first turn... It was interesting, and I believed that this hero could kick everyone's butt without exception (I would, of course, like to swap magic for ballistics, for example, and intelligence at the end for armor/attack/leadership)... I liked my hero... Now everyone is just crushing him. The old-timers keep repeating the same thing: you're eating the sandwich wrong, you need to play as a warrior, push through, take control of resources, find Utopia... All the online players know the standard gameplay, everyone acts the same, and often everything depends on the starting conditions? Does the one who encounters more Pandora's Boxes and Conservatories win? Then that's sad and disappointing... Then I'm for interesting user-created maps, where you can enjoy the beauty and originality of the idea, laugh at a joke, and replay a difficult battle... I understand that playing against a human is radically different from single-player, but I don't have time to play against real people, so is it worth retraining? P.S. If I do decide, will an hour or two in the evening (from 10:30 PM to 11:00 PM Kyiv time) be enough to play online? And to find a patient player who will agree to a game? :D
