ASW – Alternative hero leveling.

These are just malicious speculations for now, inspired by the "summoned stone elemental."

So, a decision on these points hasn't been made yet?

Because the fix should only affect the theme of this mod. And it's impossible without external changes.

Really? I suggested increasing the summoning ability by increasing education. An elf without education, in my opinion, has just as much impact as an elf with summoning.
And what are you going to use to increase summoning?

Do you know the difference between a second native city and a second non-native city?

I've already explained this in the suggestion below. In my opinion, this is an insignificant difference, given how rare the situation is. If the game is played from 2 cities, then the chance is 1/8 x 1/2 (if there are 2 classes) = 6%. If there are more cities, then nothing prevents you from developing the native city into troops and the non-native city into a guild.

Interestingly, you have a different point of view - hero classes are bad (despite the game's role-playing focus), but city classes are good. Although, in essence, both things serve the same purpose - supporting a larger number of effective upgrades for a race (in the first case, through stats and chances, and in the second - through spells).
