Future expansions.

On the contrary, the Conqueror's logic of skipping a turn is the most correct! TO PUT IT BLUNTLY, WARRIORS DON'T GO INTO BATTLE, THEY RELY ON MAGIC! LIKE, I'LL STAND HERE, LET THE LIGHTNING FLY IN THE ATTACK!

I still don't see the logic, sorry. It seems very contrived.

Or, in the sense that they will somehow help heroes cast spells.

Okay. How can a golem, having skipped its turn, help a hero in casting a spell?..

Although, the way the scale is filled doesn't matter to me.

That's actually a very important point. Your proposed option will allow the Academy to fill the scale quickly enough (even if it's broken down into small increments with high initiative for defense at the beginning of the game). I think my version is more balanced and actually suitable for wizards, it turns out to be a kind of magical vampirism (in relation to enemies) and empathy (through their own actions). Imagine at least a battle between the Academy and Sanctuary in the early stages. The scale will be filled during the heroes' spellcasting, the Nagas' use of "Honor," "Waves of Refreshment," and "Spiritual Connection," and the application of magical skills by the wizard troops. In my opinion, this is something that really fits the spirit of the Academy. And the balance isn't skewed.
