While it is by far the best meta gem for a FFB mage I must ask... what's with the retarded 2 blue gems requirement? I'm a scribe + herbalist and I'm thinking of dropping herbalism and picking up JC just because of that. The best gems I could pick out from the mass were sp/mp5 and sp/stam.
Did I miss something or is the new design philosophy regarding meta gems "Gimp 2 of your normal gems to get the meta"?
