So I came back about 6 weeks ago after a very long hiatus; since then I've levelled my Temp healer up to ~300CP.
I've been running Silver/Gold Pledges daily and other random Vet dungeons.
After at least 15 runs, I have not had a single set drop; in fact I've had ONE purple drop (crappy weapon) over all those runs.
The resulting keys have yielded some set pieces/purple drops but so far zippo in the runs themselves.
Is there a "trigger" event/quest I missed/skipped that enables those drops? Pretty much every other group member gets something on these runs; having a hard time doing the math to make this totally an RNG thing.
