Anyone put together a full set yet?

Personally I'm finding that I will pull the same 2-3 of the four available in a new quest repeatedly. For instance, I pulled piles of Ivy helix, and quivers, and a half-dozen docents of insight before I pulled the one Laurel helix I needed.

Same case with the other three quests, I pull lots of a couple items but struggle for the last one.

I definitely think the heroic set is well worth the trouble, but how odd are the loot drops? not bad drop rates just peculiar the way some items come up again and again.
