And they could sell the maps for something like 35 Law when each run in Lv.60 dungeon gives 100 Law, for example. A ratio that would practically make it trivial to get Alexandrites from maps.
Or they could take all RNG out of the whole 2.x Relic chain. Meaning that as long as you have the correct weapon equipped, every FATE would give you the required Atma, or Alexandrite, and every designated dungeon in the Zodiac stage would give you the required drop. Lights could be double yet again. That would take the frustration out completely.
Well, there's no rule saying that glamour gear must be easy to obtain. :3
