^This. I got absolutely not reason to run Low Level Roulette since it gives a low amount of Soldiery Tomestones that I can farm with A/S Ranked hunts while also getting Poetics and Allied Seals. Or run Syrcus Tower to also get Sands, Oils & UAT.
Or just do anything else that would be more productive. The fact that gear is sync'd down to the dungeon ilv slows clear speed down massively. Really not worth the hassle.
Probably why you need to wait 30-45 min for a dungeon at lv15-48 as a DPS class.
If there was something like 150 Sold & 50 Poetics and/or Allied Seals for ex, I might acually run this Low Level Duty Roulette again...
As of now, it's only a good idea to run this Duty on a fresh, first job at lv50 on a new character that needs ilv70/80+ to unlock Labyrinth -> Syrcus and Expert Roulette
