Honestly, I don't agree with this type of idea at all. Whenever I hear the phrase "Horizontal Progression" I hear "Gear Swapping". I hear people bragging about have gear for every little situation that makes them parse .0001% higher. There's no way that should ever find its way into XIV.

To an extent, this is being done with Novus Relic weapons and I'll agree that the idea should be tried with weaponry to fit individual gameplay. As a "one size fits all" philosophy, not so much.
