so i tested with only this mod and "god realm trait" mod to quickly level to max. and i found that dragon lords and giant kings lose their original lvl 16 unlock instead of this mod adding another node to the right like the other signature skills. Some normal lords and hero lvl 16 skills are also missing.

here are some screenshot for verification.
hopefully you can get around to update and take a look, i really like the variety and extended skills this mod adds!
