maybe I am too late but I was surprised nobody talked about malazon book of the fallen by steven erikson. Epic and dark fantasy with well developped characters and emotions.
Mistborn by brandon sanderson. Different approach on magic system and a lot of plot twists. If you want to get a taste of his writing before you start the serie check out Elantris by him.
Demon cycle by peter v brett. Great uplifting story with great characters.
I am ordering the stormlight archive right away after reading what you said.
