Crackling Shard: 20K Kills, No Drop – Am I Missing Something?

I will also confirm that I’ve had my shards in my WB and I can still get them to drop using the rare-round-robin method; it takes a while, but it still works. Granted I really only see one a day, but I’d rather take that one-per-day than lose my sanity trying to collect a handful as fast as possible.
