My dream:

[Waeksyn]

Damn. My secret is out. I win uncontested over 70% of my roulette dungeon drops, which I use for GC turn in to buy ventures (and to level desynth).

A single drop from a level 60 dungeon nets 920 seals. It costs 1000 seals for 5 ventures.

Hunts (ie, allied seals) are still the fastest way to get ventures stocked up, for me anyway. Convert clan seals to aetheryte tickets and the journeys between hunts pay for themselves. If you have a party of 8 you can generally spot and clean up all the 2.0 hunts pretty quick. If not, just get a good Hunt LS and do them as and when they pop while doing your beastman quests for extra ventures.
