A way to adress item-Level of crafted gear.
What I would like to see is gear that has a unique quality to them that goes beyond simple stats, these would be obtained by running content like dungeons. This gear might be job-specific and grant certain passive traits active at all times or latent traits granted when utilizing certain abilities to give an edge to the player who went out of their way to obtain these prestigious items.
Crafted gear could have similar item-Levels (with HQ's having almost similar stats), but lack any special passive or latent traits. The gap could then be bridged slightly through the use of materia to fill different roles while not being totally offensively and/or defensively inferior. This would make crafted gear an option without eliminating dungeons from the equation.
I think that coupling this with a certain degree of horizontal advancement would give content more meaning and grant players a way to diversify their gear sets. Certain materials could be obtainable through some new currency obtained through gathering and crafting content, just to get the ball rolling and deter RMT.
