Ideas and suggestions.

I hope you're thinking about translating them into the correct schools of magic?

Nope. The team believes that moving magic between schools and tiers is ideologically incorrect. It is permissible to weaken the effect of overpowered spells or make their application more difficult. Ideally, add competitors in the same niche.

Changes to the Flight and Damage mechanics were not a goal in themselves, but a consequence of fixing the "shifted guard" rule. This is a very useful thing, and it's worth sacrificing some convenience in the application of individual spells for it. Moreover, they are still very strong, and weakening them benefits the gameplay.

Regarding Jeremy, there are plans to address this.

Regarding Goshun, 100,500 skeletons from the start are effective even without necromancy; have you forgotten how it was in HotA? When evaluating balance, it is useful to compare your proposals with the HotA necromancer and the SoD necromancer; many illusions will disappear.
