In my mind yes, but I'm not carpe he might have thought of something else. But to me your title would be something that leveled with your weapon skill. Get rid of physical level, make stat distribution static on weapon class equipped with your title stat bonuses being able to be chosen when reaching the next tier of advancement. We all know gladiator will be a tankingclass due to shield, but if you gave the option at certain intervals of leveling to specialize your stat point allotment then supplement those stat choices with percentage-type bonuses chosen through the advanced title leveling, you create a way to change the way certain advance titles and base weapon classes would level or group.
That's just the first thought off the top of my head, if you could think of a better system by all means post it lol, I hadn't really thought about how people would group for content using this sytem, and also stat allolcation depending on when you do get your advanced title.
EDIT: actuallly I don't see why you couldn't allocate your skill points as you do now, but with the title system just being used to enhance the stats you have with any equipped class. It still raaises the question do you get rid of physical level though?
