Put simply, bar Temper, all enhancing magic should be Accessionble. The excuse that it should only be if SCH has access to it is ridiculous.
Temper is too powerful to be accessionable, and unlike the OP I am not okay with gimping it so it can be.
Quite frankly I agree very little with the OP, seems to just be about turning RDM into another GEO. The best idea, to me, seemed to be Phalanx II changes.
