It doesn't help that you'd need a decent supply of tier V materia to get an appreciable amount of stats out of the gear pieces, which we currently do not have a cost efficient way of acquiring.
The thing I don't get is the convoluted design. They could've just made the crafting mats (puri coke, dryad sap etc.) cost 2 Red Rowena Gathering Tokens and 1 Red Rowena Crafting Token (3 for HQ) and achieved the same effect without the tedious grind. I mean, you could maybe argue it was designed this way to increase supply of materials from the associated level 60 nodes but I generally find myself harvesting crystals instead of Citrite and Dandelions.
