ILevel or Skill level?

[Amatsuhira]

I can see the argument for people with more time being able to get farther along than someone without. However in a mere 45 seconds of giving it thought I think we could cap the daily limit and give exp or .x increase to people who stay logged out, similar to rest exp. This way people with less time on their hand would be able to skill up a stat or ability or materia at the same rate as the person with more time.
Nothing is forbidden, every idea is permitted here.
For added effect and to add to what Warlyx said these bonus points for abilities could go into a set of trees for Talents to diversify yo self.
To add to what Syvle said. I'm thinking Sphere Grid with Materia slots in it perhaps hidden, like Mutegen's in Witcher 2.
They would coincide with gear slots or perhaps the gear slots unlock the hidden materia slot in the grid which can only be seen with and must coincide somehow with the leveling materia. Or it could only become available when you have that maxed materia slotted to your armor. I'm just riffing here.
