by definition there can only be one best weapon and one best set of armour, the defining word is "best". so lets say for 2 seconds they scrap crafted and materia gear. and the "best" gear comes from "endgame" lets say there is 20 dungeons in "endgame". you will still only be going to 2 of them at maximum, because that is where the "best" gear is. making all others a waste of time
