In general, returning to the topic of discussion, I have the following to say.
Sieging a Castle has become some kind of unpleasant procedure. You are shot at by towers – the damage is minimal, but it’s still not pleasant. The entire army, except for the archers, just stands around doing nothing. Compared to the game Rome - Total War, I feel like I'm crawling around... In Rome, a siege is a siege; not many people are idle. There are ballistae, siege towers, tunnels, etc., and everyone does their job, digging, burrowing, breaking through. But in Heroes, archers attack with all their might; it's unclear why you would even recruit knights. (If they could climb ladders onto the walls, that would be a different story, or if level 1 units dug tunnels). Since the game is so complex, they could have thought about the process of capturing a Castle.
My personal thoughts:
A Castle with High Elves, Inferno. Visually, there is a chasm around the Castle; if you fall, you're done. During an assault, something is only placed near the gate (like lava), but if you lose a life, you can pass through without difficulty (if you destroy the wall). At least they could have made it more realistic. It's understandable that a griffin doesn't care what it flies over, but a peasant...
And in the Academy, you generally have to fly.
There are many inconsistencies. The developers need to come up with something more realistic.
