We already have chat.log & private_chat.log, this is not a big deal adding crafting.log as well.
Keeping people in the dark is a stupid concept in the 21st century (except maybe for North Korea)
The returns are not always Metal residues, that mean If you have pyrite for crafting enhancers and get pyrite as part of the return.. How I should know how much pyrite I got in return after my 68th attempts out of 100 on connection lost?
Starting mats and ending mats. It doesn't matter when it disconnects since you'll always have those two amounts to work with, and number of attempts does not matter for most metrics. That's why I said it's the beginning of any basic crafting log. No one is being left in the dark since all that basic info is easily obtainable with next to no work on our part. In your case it would just be pyrite + other ending mats + # new enhancers compared to what you had previously to figure net returns. I might on rare occasion use the crafting statistics menu or look at attempt #, but most of the time when I'm crafting amps or doing a large click run on something, I usually don't even bother with them since it's mostly redundant with what you'd get with a mats in/out spreadsheet.
The goal is providing information for the people who want it.. You'll never see a post on this forum about someone asked to NOT develop this or that..
We're talking more about the meta-game now. The meta-game involves tracking returns in varying amounts of detail that individual players want. It's not really MA's job to play that part of the game for us, especially for basic things like this. I previously mentioned that they pretty much stay out of that. That goes even moreso when it comes to wanting more nuanced details than just TT in/out, and it's already an exception with that in mind for what we do get on the crafting statistics menu.
When it comes to this post though, I'm mostly chiming in because there's no need for hyperbole like MA "keeping people in the dark" when the information is right there on a silver platter already to figure out net crating returns. It would be great if the crafting statistics info was sent in a message to you on a logout if the crafting window was open, but it's also not that big of need.
If someone wants more detailed information that isn't directly provided, that's on us since each of us tailors how we do tracking differently usually. At least for me, part of the fun of this game is that information is not directly handed to you. For your specific problem, it's not something we really need to bug MA about. Just look in your inventory how many enhancers and other mats you have when you're done clicking regardless of disconnects. If you start with zero or note how many you had on hand before the clicks, you already have all you need. If your spreadsheet is centered on number of attempts, there's nothing inherently wrong with that, but that's not the best method if you get disconnects a lot. I used to do that way back when I first started crafting, but moved away from that pretty quickly where I can still enter that to get a few side statistics, but lacking that number does not make the rest of the spreadsheet fall apart.
Overall, the point is that this is not hard information for players to get, but it won't necessarily work if you lock yourself into only getting it if it is presented in a certain way. The easier solution right now is to change how you do your spreadsheets or how you manage your inventory before a crafting run. That's just a reality we all deal with playing the meta-game at some point when we realize our personalized spreadsheets aren't meshing quite how we want with the game.
