As always, a helpful guide. I never paid close Attension to the Exp from Master Writs, good to know that the Blues give the same as Purps, makes buying character leveling cheaper.
A note on leveling Enchanting, player made glyphs on the same account have the same exp as other player made, and mob drops. As long as one character makes them and another extracts them. Since the enchanting skill levels just as much for making glyphs as deconning, you can level two characters at the same time, and use the bank to ease deconning (no need to withdraw first)
Use White Glyphs for the first 5 to 8 levels, Greens up to 15 to 20, Blues up to 30 or so, the Purples for the rest. Dont forget to learn the Essences and Potencies as that gives a nice chunk of inspiration.
You can buy Potencies cheap from an enchanter, cheaper than usually found in guild stores. Which is strange to me. I tend to have 1000's of CP160 Potencies, so I just use those.
Once I leveled a crafter just using CP160 Legendary (Kuta) glyphs. There wasn't a noticeable change in the number of glyphs required to level that would warrant the cost of using Kuta glyphs.
