I hate inscriptions and it's my least used profession.
I don't think I ever sold an incription and eventually vendored all of them.
I can make scrolls for my enchanter but the last time I needed those I just bought them off the AH.

incriptions are overly complicated in that everything is two or 3 levels away ( you need an inscription that requires a particular ink which requires a particular pigment which comes from a particular plant of which you need 5x of them ).
with alchemy you need only need a particular plant (i.e. soooooo much less complicated )
I would rather have 4 hours on a flask myself via alchemy

I still have the inscriptions on one of my team but I haven't used it in months and I will never level up another one.
unless they come out with an inscription that works just like a alchemy potion or an enchanter directly then I won't bother with it again. ( scroll of intelect is ok, they need better ones )
