Is there content where you would you run only a single Drac instead of 0 or 2?
0 for content where drops aren't a thing at all (GO), 0 for content where drops don't really matter (raid events) and 2 for content which you can do "gimped" (Advents)?
... I guess running Drac+fluffy could be possible for Accessory quests? Does droprate+ help there?Oh yeah, I guess that's a possibility for those who have 3-star+ gacha Eidolons.
