While quests might be nice, Royal, it also takes more work by the devs to implement. Also, I'm sure a -lot- of players would complain if it had to do with Helian/Lunus especially since one cannot switch sides. All Helians are not spellcasters and all Lunus are not melee-ers.
I personally would much rather it be what it is now: a change to the base stats of the Dragon Adventurer school.
