I like the idea.
I'm just curious of what would be the impact on playing the basic jobs.
More specifically, say your title is Paladin. Do you start PLD rank 1 and earn exclusively PLD skill points?
If those "titles" become the norm and the basic classes are just used to acquire abilities, will they be desirable in exp parties, missions, quests? We will still need to take them to a high level to get those stronger abilities but will they still be competitive at a comparable rank?
I'm not saying it could not work, I'm just curious
