In the SPIRIT of an event it should permeate all things in the game... make it rain currency in even non-dungeon activities to celebrate this. Sure > the dungeons should be the ultimate source of earning weapons and currency but why not running playlists... randomly on patrol chest/public events... you know use that janky RNG engine for good and start raining coins. This avoids the feeling of "needing".. not using forced but could apply... to run a dungeon but "choosing" to run it to optimize RoTN drops... which is more positive for players, imo.
