Hehe nice to know Goodnight!In my experience, no. As a leatherworker, I manage to make a good 40 bits of crafted gear (only form the leather obtained from levelling in 1 day) melted it all down into Obliterum and I had plenty. A bit of focused grinding (as is always required with these things) and I'd say you could have 10 Obliterum/hour as a LW (with rank 3 patterns ofc) I sent it to my monk, whos a JC. I don't know wtf is going on with JC right now, but over the entire time levelling I aquired enough gems to make... nothing.
Dependant on proff, you can make a tonne of Obliterum very easily. I'm making my Monk an LW in preparation if JC goes live as-is.
Edit: Don't expect a reply, going to bed. Nighty Night.
