Played over 50 iron banner games on hunter for the two times in was available. Still didn't receive all new pieces of armor sets.
Also getting a lot of drops from regular crucible and battlegrounds. So the loots is not iron banner exclusive for some unknown reason.

Same problem with my hunter. Completed weekly challenges on both weeks (18 + 18 matches) plus a ton of additional runs enough to gild the seal, being close to resetting the rank a third time, and leaving all the rank-up engrams for the hunter.. But still haven't got the chest armor to drop :( Compare to my titan who got all the armor pieces in something like 9-12 matches, as just match completion rewards.
