The other night after fractal daily/recs were done, I was opening my chests when I noticed I had 133 Blade Shards in my bag (https://wiki.guildwars2.com/wiki/Blade_Shard) and I have no idea how I got them. Aetherblade was one of the daily fractals, but the wiki doesn't mention them dropping in that instance, and of all the times I've done Aetherblade, I never got shards (or at least this many). The Druid in my group said she got 99 shards as well.
