Updated desynthesis guide

[Kamatsu]

As far as I understand it, you can desynth even if you aren't in a relevant profession, which means it's still governed by item type. Fish for example will level up CUL desynth but I don't need to be in my fisher to do that. Anything, even DOW/DOM will do it.

This is exactly how it works - you do not have to be a specific class to desynth an item.
- IE you do not have to be a Carpenter to desynth 'carpenter' items.

Instead you can desynth any item regardless of your current class, and the desynth xp will go towards the items respective class.
- IE if your currently carpenter and desynth an 'armorer' item, you will get xp towards armorer desynth skill (assuming it's not too low an ilvl item) rather than carpenter.

The only exception is regarding the weekly Desynth challenge in the challenge log. It will count any desynth done as any class, but you will only get the XP from it if you are a crafter class under 80 when you complete it.
- IE if you desynth as a DRG and all your crafters are lvl 70... you will get the gil reward but no xp.
