It's a bit of a conundrum because alot of how you diversified your character from others was often your gear choices. It's hard to differentiate yourself from others in XIV because there is 0 real diversity to work with.

You can't work on your Solo Evasion set, instead of beefing up your SATA gear. While I think gear is the wrong way to go in terms of larger diversity, the game really does need some depth to it. It's extremly shallow as it stands (Let's hope 2.0 fixes this a bit) But I can't imagine it will at launch.

We need something like Merits (Well thought out, so that it's not just a cookie cutter merit setup) Let people be creative with how they want their character to stand out from others preformance wise, encourage people to focus on only a few classes instead of encouraging people to slog through all the classes just for the cross class skills making them play something they don't like. If I want to be the best Blackmage I can be...why should I have to level a healer? FFXI actually had the same problem with the sub-job system but at least it capped out at half the max level making the trip rather short to a sub-job.

Hopefully when we play 2.0 my Dragoon might play a bit differently than the next Dragoon standing beside me.
