Not really. Supposedly, the higher level it is, the higher chance you have of desynthing the rare drop. Like, if you are farming EXs and you get a lot of weapons, if your desynth is higher you're supposed to have a better chance of getting the crafting material which is eventually used in the glow weapon and can go for 1m or whatever. I don't know if that's true, because even if it's maxed (I know I'm not maxed now, but I have been in the past) you don't get it all the time. Still, I desynth the stuff that I will gain levels for desynthing, because I have basically zero use for GC seals.
