After some careful discussion, the admin team has decided to leave this as is. We believe the inconvenience is minor for the small gap in levels, and in some cases is operating as intended. The debate sways more toward wizards likely needing more hours to rest at higher levels to depict the the need for more time dedicated to memorize harder spells, and less time at lower levels where sorcerers would simply need time to rest physically (which, in my own opinion, should vary as well to depict different levels of exhaustion in relation to remaining spells).
This would, to depict correctly, include lots of coding and new systems, and to then recheck currently working systems. We just don't have the spare time for that. I can barely kill Shark in a timely manner these days.
In short @Bowser we don't disagree, but its working fine right now, and would take too much time to resolve what is effectively a coffee-break between some quests at earlier levels
