deep dungeon in duty finder?

[LibitIncarne]

It takes too long to use the built-in queue for Deep Dungeons

Party Finder. This also allows you to keep Magicites/Demiclones/Pomanders between floorsets and allows you to go beyond floor 100 (PotD) or 30 (HoH/EO).

I turned Matchmaking on for Variant Dungeons and it's taking ages to fill the party

Party Finder, or just solo it by turning matchmaking off. The only reason why it would take longer to do a Variant Dungeon solo rather than in a party is if your personal DPS is substantially lower than expected due to the HP for all bosses and enemies being reduced to adjust for not having as many party members.
