Highly dislike the desynth system

[Kaaylryn]

I have only started to dabble in desynthesys. I assume that people want to be able to desynth cloth, leather, metal items, ergo the need for more than 1 at max level. However, desynthesys is only good for going after the elusive Master Demimateria and some lesser grades for crafting some items.
So, I have to ask, if the demimateria is the only thing one is going for, why not just level 1 job to 100, get the Master Demimateria required to get the tools and be done with it? There may be something I am missing, so please enlighten me.

You're correct that basic clear, field and battle demis could be obtained from any class (except CUL which produce only clear ones) and having only one or two maxed or at least leveled to high 90 will give you access to new recipies and tools however the main point of specific classes are unique items received from high level desynths like swimsuits from CUL and so on ...
