An update 3 days later. I've been keeping exact track of what i've been getting. I did my first set for sunday 4/21, and since i've been keeping track, i'm 4/55 on badstilla, 2/25 on carth, and 2/20 on juhani. Coincidentally that adds up to exactly 100 sims, from which i've gotten 8 shards. 8 lousy percent.
I can understand one off day, but to have a run of days this bad is ludicrous. And this is just since i started keeping track of it to prove to myself I wasn't imagining things. It was like that for several days before i started keeping track.
It seriously has me considering just quitting the game entirely. If they're going to cripple the drop rates that bad, then why would i bother? I'm averaging less than a shard a day on everyone. We can round that up to 1, and i'm still not going to spend another 6 months getting the 140 - 160ish remaining shards i need for each of them.
