I want to see "class" gear bought from marks or earned from quests. I want a cool hat that shows my character has leveled THM. I'm fine with it being equippable on all jobs after, too. Just make them favour only the right job, or at worst, compatible ones.
Marks, definitely. As it is right now, at least in the case of the Disciple of War/Magic guilds, once you've saved up the marks for the minimal amount of job skills/abilities/traits, you don't have any reason to earn any more. This can become frustrating when you have no choice but to earn them when choosing leves, too, due to the rewards available to you.
I wouldn't expect anything as epic as, say, the AF armor of XI from mark spending, mind you. But something you can actually get and use during your ascent to Rank 50.
