But doesn't stealing them from a friend in private ooc'ly also defeat the intended point for the class? Most people to my knowledge play ST as a "build-your-own mage" type deal rather than actually playing into the class gimmick (an unfortunate consequence to how clunky stealing random spells is in an actual combat scenario). I personally don't think just resorting to the idea of "just grab a friend" to be ideal every time you want to make small adjustments to your spell lineup (or accidently lose spells to class changing, LE, or spirit loss) is the best way to go about it. 

I remember seeing the idea of having a menu where you can re-equip spells you've stolen in the past as a possible fix to the issue from a QoL standpoint, while not eliminating the spellthief fantasy from the equation. Something kind of like the FFXIV Blue magic menu is what I was thinking of. It might also help rectify the issue of people not using spell snatch/snatch spell in actual fights due to messing up your desired spell lineup, since if you can reslot things after the fight I feel people would be a lot more inclined to do so.
