10% to extract each type of runestone when you max out the passive? That's really doo doo. I'm not saying it should be 100% chance or anything like that but 10%? Come on now. It's actually kind of a waste of skill points IMO. I get a VR16 glyph that I can't use so I do the extraction and get a Ta. Seriously poo poo ZOS. Seriously. Poo. Poo. My max level crafter, who's 50 in all crafting, can't get more than a Ta out of a glyph? Even if it were a 50% chance, or even 40% or something like that I feel would be fair. 10% is just seriously too low.
