RTF is a global modification that replaces all towns in the game.

It would be much better if werewolves looked good for the Chimera Mages on the fifth level as offensive infantry; then, spellcasters could be moved to the third level, but still given a small bonus and made very strong (in my opinion, this is logical; in a city of mages, mages should be more accessible than for dwarves and other non-magical races).

I disagree with you about moving the mages down. Yes, on the one hand, they should be more accessible than for other races, but on the other hand, they should be stronger than the priests of other races. After all, unlike the priests of Erathia/Malassa/Urghash, etc., these mages practice absolutely any magic. (because, as far as I know, there was practically no forbidden magic in the silver cities, and our wizards of the House of Chimera are precisely from there.)
So, I suggest thinking about who to put on the 3rd level of this faction.
