Imo SE is trying to further weed out the non rich and dedicated crafters.
Think of it lol, they are making desynth so that you should focus on a few classes rather than all crafts and the fact that they are raising the bar for crafting.
I guess SE was like ppl had their fun with easy vanya HQ etc and now a lot of ppl are starting to become master crafters, so lets give em a good ol backhand and raise it further so that only true crafters will continue to progress their crafts.
