ASW – Alternative hero leveling.

Don't you see the difference between leveling up and the starting town's guild?
The primary school is the one that is primarily supported by leveling up (through skills). And town schools are a separate issue.
For example, why would I need your tricks with towns if I capture several other towns in the first few weeks and easily get in the guilds what wasn't available in the starting town? Or learn those spells on the map? It will be easier and faster than returning to the first town.

You never consider many aspects, seeing only one. First, the class of towns is determined for all towns at once; second, even your ideology of capturing a town with a different guild is absurd, because leveling up each subsequent town is already an element of strategy; third, in the later stages, you can obtain almost all the spells you need on the map; fourth, you would break the strategy on the global map, where a town is a key point not only for generating an army but also for spells (heroes are RPGs, no, I haven't heard of that; there are Knowledge Banks for reducing the speed and influence of spells).

Is "imba" something that plays too strongly?
I need exactly those schools in which it plays more strongly. That is, those that best suit its gameplay, that best reflect its nature.
And questions of overall balance (where to increase, where to decrease) are already a different topic. Reduce the blue archers to an adequate level, and it will be profitable.

I don't know how long I need to keep hammering home the idea that the mod doesn't affect your projects, and since it doesn't, it's built for 3.1 – that's obvious. No, we need to stir up everything around it, just for the sake of a subjective point of view.
