I've been doing a single map hunt per day as well since its launch with my hubby, and i can confirm the worst drop ever in a mmorpg.
You arent that unlcuky, the drops are very very low.
Never got a minion nor a goatskin item reward, only a grass a single time.
Maybe that mithra over there have a point, and sure hunt with FC group must be the way SE wants us to do it.

Peace out.
