I'd like to start out by saying thank you for contributing this additional guide. It helps the player community greatly to know all the benificial alternative ways to achieve the goal of obtaining that next level in crafting. While I do understand this method is effective, in my own personal experiences crafting, I chose to present my own method of straight Crystal to material form of skilling up. Reason being is, the vast majority of skill ups obtained through Desynthesis is largely 0.1 per attempt when the skill up actually takes place with the common 0.2 skill up occurring when you are at 0.8/0.9 into the level itself. That 0.2 pushes the next level obtained. Then it's back to 0.1's again. In my method, you receive 0.2/0.3/0.4 skill up as a common. Just the other day I went 10 Lvls in roughly 2.5hrs vs the Desynthing Butterfly Axes to achieve 1 level in 1 hour. Using your method allows the crafter to break down the item made back into materials. My method allows the crafter to npc the item made at a near break even cost to be able to repurchase additional materials for the next synth (rinse repeat). I see both methods as being a viable way to achieve success. The one thing I don't agree with is telling people not to farm materials as this serves no positive outcome for a new starting player with no Gil to begin crafting. Not everyone in this game has a Gil tree in their Moghouse to blow on auction house mats. Other then that, thank you for posting your guide.
My guide has been moved to the official WikNas page. I also acknowledged your guide as an excellent source in the method of Desynthesis for skill ups and directed them to this post for further information.
In my experience I got huge skillups desynthing. The point of not farming materials for crafting, is that it is almost always more efficient to farm other items or gil itself that sells for more worth than farming crafting mats.
Example, if you're synthing bird fletchings, it's better to npc farm 20k/hr gil than farm bird feathers, as even at 2k a stack. Farm 20k gil then buy 10 stacks of bird feathers. You won't ever farm 120 bird feathers in an hour. If you can't farm that much npc gil/hr (check out my starting gil guide, it lists where to do this) then you shouldn't be crafting. Crafting and farming and gil and time are all related. The best method is always buy the minimal nq gear that matters, get higher levels (because it opens up higher gil/hour farming) use that gil to buy materials to power crafting (the easiest and most efficient way, which is pretty close to my guide) to get higher levels, because as soon as you hit those higher levels of crafting, all of a sudden you open up the proper hq tiers to make gil.
