Least favourite occult

What disappoints me the most in spellcasters is that all their spells has the same color and gestures even if the game confirms they have come from different natures, having no festivals and rituals, like for turning into a spellcaster, and i really miss their ability to change appearence (like aliens) and turn into animals (like bats, birds, rodents).

The fact that they went to an artsy aesthetic and didn't added an altar for crafting really saddens me, because it would match so much and give us gameplay.
