Some Emphs can probably be done faster but not all of them. Also have to consider that as you do WoE your going to amass a pile of all the different types of coins "Looking at you Coins of Ruin", though with the elimination of personal chests this might change. Doing a emph for your main or favorite job isn't that hard but if you play a spread of different DD jobs WOE weps are a good secondary option. Basically it all comes down to what type of group you run with play time bla bla bla as to which option is best for you.
