I did 6 quests today for my dailies (3 Gridanian, 3 Thanalan) and received a bunch from that. Sent both retainers out on an exploration for the cost of 2 ventures each (chose the longer, 18 hour one over the specific item.) Supposedly, there's a chance of getting a rare or unique item that you can only get from ventures. I'll check tomorrow to see what I got.
