I love the ventures. It is a nice lottery, can be a letdown or something very nice. I have Miner, Botanist, Fisher and Paladin on Level 30 and so far they brought:

- all sorts of housing and crafting materials
- unsellable personal items (green items below level 50 you can use or trade for company seals)
- Militia armour iLevel 55 HQ
- Materia 1-4 (very nice)
- Ifrit weapon for WHM
- loads of crap (NQ fish, single items)
