There were no changes in the original, it's probably been around for 3 years. Therefore, the change, as in version 1, in my opinion, only slightly increases the pace, plus I like that, for example, on some map, you can get the missing oil, or, given potential resource problems in the future, instead of building an extra 5th level, you can focus on getting Town Portal.
7 is also not very critical; it simply allows you to level up your main hero or take a risk and get a useful skill (either for the main hero or for another hero).
In general, I really like the current state, and I am in favor of supplementing the HW rules with these changes.
I don't think it's necessary to introduce a bunch of extra options.
Some people obsess over every little detail, and if you listen to them all, you shouldn't change anything at all.
The "rebuilding" mechanic was not invented by the developers, and it can be improved in any way. Opponents of this are simply too lazy to learn/get used to the new system.
Perhaps some people won't want to accept even these minor changes, but there will also be an influx of new people/the return of old ones.
I am sure that there will be those who will not accept even adequate changes to the generator, which will make the generations as the authors intended them to be, rather than what is happening now with incomprehensible paths, bugs, and endless one-way roads on HL+U.
Completely removing one-way roads may not be necessary. But the option with one or two roads leading to the exit should be excluded. If it is not possible without removing them, then what can you do? It's better to remove them.
Regarding the Wizards, the only unpleasant thing is that it shows the presence of magic. You can use a hero with high Wisdom to gain control. Maybe show whether it's a skill or not?
