While it is quite possible to level enchantment, it is the slowest craft to level, as many people have noted. Yes, there are ways, but it is definite!y the ugly stepchild.
My suggestion is to allow xp and either glyphs or runes to be extracted from any existing enchanted item. The xp should be low and it should probably drop runes because glyphs would bypass the craft entirely, but istm that this change would put enchantment on a much more even footing with the other crafts.
This also seems 'sensible' to me in that deconstructing items *should* be a good way to get 'inspiration'.
