Just spread them out and don't take more than one at a time. Don't go at it looking for a particular drop. Just occasionally pop and play as normal. Gotten a Few decent drops. All in all tends to balance out to about the same price as buying an armor piece. Except you can get more than one particular item and longer than a weekend. I like them. A nice way to make the same ole grind feel interesting. Strikes became more fun for sure!
