I agree, that would be a simpler, more direct solution to the worthless distillates, but it had already been suggested, either here or in the Agent System Feedback thread, and maybe they made these impure distillates in the first place because Purified are too good a reward for tier 1 missions. Introducing the alchemist both explains a bit about where it’s all coming from and gives them an option in between full shard cost and no shard cost.
And it doesn’t have to be complicated, either. I threw in a bunch of possibilities because there are a lot of ways they could adjust it to the cost balance they want, but it could be as simple as sending an agent on a daily special mission to get an anima still and dumping your junk distillates into that instead of throwing them out.
I would love to see all the agents bring back only purified distillates, but I’d still want to know where they’re getting them from.
