I was never really a fan of the whole tomestone system in general. As an idea I like it, but having to phase out tomestones and having so many sets seems very silly.. I always wondered why not 1 tomestone set for the entire expansion that can be upgraded 2-3 times.

For me, I'd rather horizontal progression actually be a thing. Like, as a BLM if you melded enough spell speed, or got a set that did spell speed, it would significantly reduce your "turret mode" time; alternatively you could up the damage. End result in a skilled players hands would be near identical DPS, just larger-slower hits vs smaller-faster.

Secondly, the final tomestone sets are stupid easy to get at the end of an expansion, like the Shire set in 3.0. I never really understood why they could carry you about 1/2 way through the next expansion.
