I'm actually in favor of both specialists and the desynth caps, as they perform the same essential function that raid lockouts and tomestone caps perform for battle classes: It creates a maximum amount of "sunk time" that you can invest into crafting/desynthing. This is the same reason that SE has gone to a decent amount of effort to make it difficult to shuffle items between characters on an account.

The failure only comes in that the results of crafting and desynth are focused around a very small number of items in a small number of classes, creating an artificial utility restriction on going against the preferred specializations or desynth classes. Rather than remove the cap, I'd rather see equally accessible MC demi desynth items for all crafting classes, as that would fix the core issue without creating a meta-environment where you're expected to have every desynth capped.
