For those stuck at 29, I feel ya, it took my 5th raid to get my 1st armour piece. Then suddenly the week after I got 2 more and just filled in the 4th with an exotic.
It can happen that quickly!
I think Bungie will be changing how you get gear in The Dark Below, as they have stated that you can "earn light" through Eris, the new vendor/story mission/etc. person.
So it is likely that you can earn the gear to get to 32 via bounties, missions, quests, etc. instead of random RNG. Similar to how the Queen's Wrath and Iron Banner worked. Plus Iron Banner will be a new way to get to 30 as well, I just don't play Crucible so I won't care about IB.
