I have noticed that there is a slight discripancy in the distrubtion of the tome-rings. Every physical class be it tanks, dragoons, monks or Bards can buy another ring for tomes and thus gain ilvl 100 (without going the 2nd coil of Bahamut). Spellcaster on the other side are limited to one ring only because it is either for Summoner/Blackmages or Scholar/Whitemages.
My idea is to add a ring with neutral stats for the mages. The stats every caster class need would be piety, spell speed and critical hit rate.
I think that would enable casters to reach ilvl 100 without going the 2nd Coil as well.
If you were to consider my idea I'd really appreciate that.
