UNIT - Creature Balance + Visual Changes

In general, an area-of-effect attack is much better than a retaliatory attack (retaliation can be countered with single-target attacks); moreover, in terms of other stats, Kshatriyas are significantly superior.
I am considering the effectiveness of abilities against humans by default; how they work against AI is not as important to me.

I agree. Slowing/speeding up combined with blinding is a minor trick, not a spell; at the same time, Chain Lightning (available after eating) is a balancing necessity (anti-hit and anti-blind).
Furthermore, in my mod, the concept of "not casting spells" is expressed even more strongly (one type doesn't cast spells, but only debuffs with an attack; the second type inspires and prays, doesn't cost mana, doesn't depend on magic; the third type casts situational light/dark spells that don't depend on magic). Because personally, I don't agree that shamans have spells that depend on magic, even if they are simple speed/slow tricks. What about blinding?

In order to have something to test, you need an appealing option, not just guessing.
Experienced players already understand what Arabs with 7-10 are like, even without testing.
If a new unit is offered (new abilities such as piercing, maneuvers, retaliatory shot, etc.), the appealing option will be the one that doesn't duplicate existing units (centaurs, succubi, mages). But that hasn't been offered.

Translation: you don't have the time or desire to balance anything. Because any balancer listens to the opinions of experienced players, rather than ignoring them. Arguing is not necessary here; it is enough to take note, analyze, and draw conclusions. Instead of taking criticism personally, defending yourself, and making excuses.
