One problem that I can foresee in MRQ2 is that quirky skills & spells will be neglected, since IRs are a valuable commodity. Is this true in practice? Of course you will always get dedicated roleplayers who value style over substance, but I'm wary about (effectively) punishing people for having interesting characters.
If a character acquires, for instance, a magic feather that allows them use of a Fly spell, be it sorcerous or divine, that has its own Lore or Grimoire skill. Sure, it's nice to be able to fly, but joining the True Malkioni Church is a much better choice, if you're already a civilized Malkioni character.
