I understand there is a limit to desynthesis rating and if you raise some too high, another one will drop.

Currently my culinary one is my 2nd highest (Leatherworker is higher), am I am trying to raise 2 other ones (blacksmith and Goldsmith) above my culinary one.

I want to lower the culinary one, but NOT the leatherworker one.

If I raise Blacksmith and Goldsmith to a certain point, will the leatherworker desynth rating decrease automatically? Is there any way to avoid this?
