All fish have a value in the system. There might be an issue with the measure of obsolete and the quick nature of it. Many fish are a victim of that but I can't find inventory to save them anyway. It's easy to throw them away.

I'm not saying I don't want processed shards back. I do, I hate shard grind but for fishing I suspect we might end up seeing a vendor exchange system for shard to fish. It's very likely we won't ever see the Alch recipes brought back.
