Martial Prowess (progress concept)
So I thought I'd mock-up what I consider an interesting concept used before in other games & in FFXIV's PVP system - this is Martial Prowess; and I envision that it would work in such a manner that once you have capped your physical level you could accrue points via completion duties, trials, leves, and FATE (AKA playing) to further adjust or Job abilities and traits.
I do not know how, or even if Square Enix would consider implementing a system like this - their stance on simplicity of concept and ease of access has been very clear.
I do not know if people want this - I don't presume to speak for anyone but myself.

A system like this already exists in the game for PVP Skills and Traits - upgrading as you rank up: PVP System
It's been done in games like WoW with Talent trees and FFXI Merit points; Merits Talents
I know a lot of people will say "illusion of choice" but I feel like FFXIV offers enough variables in content, player composition, and player skill that a system like this might be interesting; there very well may be a "best" combination of upgrade choices but this might not be practical for all groups/players/situations. I enjoy FFXIV very much and I understand the Devs. are trying to keep the game simple with very little variance in their vertical gear progression and accessible gameplay - but the game might be more interesting with some depth to endgame character growth.
