Are there any other tradeskills where a trivial 60 recipe costs over 180P per combine? 150P or so of that is Aqua Regia. Or I can spend almost exactly the same 150P for Aqua Fortis and Vial of Muriatic Acid and try to make my own... Oh wait, if I'm trying to skill up with a trivial 60 recipe, how likely am I to make Aqua Regia with a trivial of over 100??? Really, did someone just slip a digit and type 74.36 instead of 7.436 for Aqua Fortis, and similar for Muriatic?

If it wasn't for the insane cost, the various Solution recipes would make an OK skillup path for Research, at least up to around 100 or so. Most of the other tradeskills have some vendor only recipes up to that kind of level or better. Worse yet, Aqua Regia is required for almost every paper-like (paper, papyrus, vellum, parchment, etc.) Solution (26 in all). Could we get a price adjustment on the components for Aqua Regia? 90% off would be a good start!
