I'm borrowing the idea from Aion, which I found fairly nifty and not exactly game breaking and actually is an incentive for collecting titles.

As we know we are getting visible titles on our characters in A Realm Reborn.
How would you feel about small stat bonuses on some titles?

As long as no singular titles become overpowered compared to others, they can be a way to further customise our characters beyond stat allocation and materia.

If I were to complete the paladin quest-chain and gain a title like "Unbreakable" it would be nice for it to give a bonus to my defence or vitality.

I think it would be fun, discuss!
