Wish I was more familiar with Jane Thor to be able to discuss.
Inza was actually my favorite version of Fate. Some damn good stories with great characterization. She was vastly less powerful in any destrictive sense than any other version of Fate (blasts and direct attacks did literally nothing) but SOOO much more creative in how to use magic and get the job done.
I also liked the bit during her run when they basically made Kent his old half helmet self (brick with blasts and flight etc) when she was missing.
