What don't you like about Chaos magic – essentially, isn't it ice and fire magic?
If I'm not mistaken, there's a skill in the 5th game: fire warriors.

What do fire warriors have to do with it? - The perk increases the effectiveness of the "summon elementals" spell; moreover, only fire elementals are always summoned.
Chaos magic is a bad name because of the association with Inferno, which is not justified in any way. In reality, we have magic of destruction.
Why did Chaos become fire and ice? - In this school of magic, there are all the elements, but in their destructive form.
