I actually have not tried it, I have 16 inks so far and it seems like it'll cost too much to get wrong. I'll wait for videos on other peoples successes / failures.
Would be nice to have an option of crafting without inks, but it only lasts 30 minutes, so we can actually go out and try it before committing. A bit like using a pencil, before we get our pen license. Or having a testing room in the Scholarium that you can try out all combos for free, but only pay the ink if you want the changes to continue after leaving the Scholarium. I guess we have this, it's called the PTS, but can we get something similar on live?
I've also noticed I'm now getting spammed with Scripts that I have already read? Is this going to be another spam fest for our inventory? I'd rather it just be read once and account wide access, then never drop again to prevent being bombarded with that.
