Keep in mind you can desynth the NQ's if you've got desynth leveled in that craft, so they aren't a complete waste. Honestly, Mithrie's crafting guides have been the most help to me out of anything. https://www.youtube.com/user/Mithrie

Remember these are the hardest synths in the game right now, and it is very hard to get a quality, so you're gambling on <50% HQ chance alot.
