I would rather see a system added where the choices you make allow for more customization of your job rather than mandatory improvements like "increase dagger skill by 1 level per point". Since they are working on large scale content, it would be cool to see a system that gives you a wide variety of additional abilities - allowing for example one bard to gain abilities specializing them in caster buffs and another bard to specialize in melee buffs. Allowing players to change the options they picked would be key, of course.
