Funny enough, you are very similar to me on dcrops chest rewards. I should have never opened all my packs, some months ago... that was a very dumb move! I would be around 30-40 reward chests per season now. :D Anyhow, now I am using both the DCROP:SWAP.HIVE pool and any packs I win, to grow back up again.
It's one of the best source of goodies, those rewards, in conjunction with all the rest you get just by combining/holding rewards.
