However, because of what many consider an oversight in how skill gain is implemented for spellcasting, the unmodified game requires a great deal of tedious 'practice spellcasting' of small, useless spells to improve magic skills. Morrowind's skill system is intuitive and well-designed in many ways. For now, I'd very much appreciate feedback as to layout and so forth, as I'm experimenting with that.
