I've many spell fragments and can make much more. Have only 1 moonstone library. So i think i'll be happy with this, but it depends a little bit on the fact if other items get less frequent in the MA with these new items. Anyway first impression looks good to me.*sigh*
I suppose as a reaction to the complaints about fragment overload it seems like a good idea. But I think it is a bad idea, because who has the fragment overload problem? It is the players who own from 3 moonstone sets upwards. These players are already unduely overpriveledged for reasons I have stated in my post about the shortage-of-fragments-problem and the moonstone set problem. Now exactly these people are getting even more advantages, but the new players have to endure another useless recipe blocking a slot, where there could be a pet food or a tourney booster. No, actually I think it is a profoundly bad idea, sorry.
