I think the only advice I would have is bang out public events (destinypublicevents.com). You get a shard or energy for the first one each day. Each event can also grant shards and energy. I've had stretches of getting a shard or energy 3 out of 5 events, and I've had stretches of 10 or 12 in a row yielding nothing.
And I'd recommend buying armor from your mentor if you can. Buy more and breakdown if you can and need shards.
When you open the Nightfall or weekly lvl 28, I'll help out any time and walk you through it if you need it.
I play a lot of 24 level Strikes. I've gotten lengendaries from the end round dice roll quite a few times now.
If you got the strange coins, buy an exotic weapon or armor this weekend, which ever you are missing. Buy an exotic engram to break down if you have a bunch of coins.
ps. Here's how I approach exotic bounties. I hit square to abandon. Done. lol. I can't stomach the time in the crucible.
