Updated desynthesis guide

[DPZ2]

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.

Caveat for those reading this:

You still have to be at least level 30 in the appropriate crafting job in order to desynth an item.

You don't need to switch to that job in order to desynth an item.
