is it now a fact that grinding a dungeon is faster lvling than fates? considering most dungeons at low level took 45 mins and armory bonus doesnt apply to dungeon completion (only kills made inside the dungeon) also if you have no rank 5 fc you can get their exp bonus and you have rested xp. whereas fates you can do about 5 in 45 minutes armory bonus applies to both mob kills and fate completion then theirs you rested exp.
keeping all that into consideration is dungeon grinding now better than fates even with dungeons getting exp boost?
