ASW – Alternative hero leveling.

You shouldn't draw general conclusions from a single instance. First, we train archers, even though we don't need them, and then everyone else?

I wasn't suggesting a linear progression of "Archery - Battle Madness." Battle Madness can be derived from level 1 tactics, for example. And it doesn't enhance everyone; it only affects low-level units (the rest receive a negligible bonus). Tactics is a widespread (non-specific) perk.

Don't you think that humans and demons don't cast Berserk or Subjugation? That's surprising!

Not with the same efficiency. I'm talking about the distinct differences between a demon and a Tower Elf. Subjugation is a completely different thing for both. In other words, their "Darkness" characteristics are different. Demons and humans primarily focus on debuffs, while Tower Elves focus on manipulation (and plague).

By slightly increasing the chance of summoning and choosing the right city class, we can decide where to develop – that's all.

Not slightly, but by 8% for each of the 3 "native" schools. 5% might not be enough.

This can be achieved by lowering the elf's education to 2% and increasing attack to 8% (or both by 5%).

However, we need the opinion of active elf players here: I haven't played the original game in a long time, so I can't assess such a change.

By the way, an elf can learn Chaos spells from the Secrets of Chaos and guilds of levels 1-3. So, the issue with city classes is not essential here.
