As far as arpgs go this games crafting is relatively inexpensive try crafting top tier gear in something like path of exile it can take thousands of tries. I actually like the crafting on this game a lot. However having a list of possible mods for each slot would help a lot and would make this far better. 

edit: Im also not seeing any shortage of relic tier items to scrap at least 1 every other mission sometimes several in one mission. considering it takes less than 5 minutes to run even the longest missions this is a very generous drop rate.

Hey there. So I suppose I'll offer a different viewpoint. Ultimately, gear in APRGs will always have an element of randomness, and randomness must be limited by *something*, otherwise the game just becomes a matter of how many times you need to press a button before you see its maximum value. Crafting is no different. Doubling the reagents for crafting just puts us at a new equilibrium with respect to what how many random rolls you get before you run out of materials. It's sort of like doubling the amount of money in a system---prices simply inflate to fit the new value. With extra mats, gear expectations simply rise to meet the new availability.

I actually like the current balance of crafting materials. I feel like I always have enough Ancient Mechanisms to experiment with different items, so I can always try things. Machine God's Sparks are common enough that I always seem to have enough to add crafting capacity and reroll relic enchants, but not common enough that I don't feel excited when I see them drop or feel the pinch when I am modifying archeotech relics. When I really want to invest in a piece of gear, I do feel like I need a pile of Sparks, which does require some stockpiling, but it also makes the resulting equipment feel valuable. If anything, I feel like I'm always running out of credits, which feels a bit bad. Perhaps I just experiment with new builds too much which drains my credits on test gear.

As for Kiliak's comment on knowing which enchants can roll, I use the config files (online here) and the language files (<game directory>/Strings/<language>/Lang_Artifacts.xml) to check. I am not suggesting that this is a *convenient* way, and it would be great to have a much easier-to-use reference, but in the meanwhile, I hope this might help you save mats and get what you want, from one player to another.

I also am not sure that I like the idea of converting low-tier mats to high-tier ones, because that means that low-tier mats effectively contribute to your overall crafting material limit. This weakens the rewards from harder content, since the crafting rewards could just as easily have been farmed from easy content. This pushes things towards a "farm fast" rather than a "farm hard" environment, which I don't particularly care for. Path of Exile got pushed pretty hard down that road, and now a good chunk of the endgame has been balanced around builds which have extreme movement and clear speeds. It narrows diversity. If we take the "convert mats" approach to its extreme (by automatically converting mats before they even drop), we get a game where there is only one crafting material. I feel like that would oversimplify things, since it would boil down to "get more money, spend on gear" as opposed to a system where you might try to prioritize certain rewards over others (via choosing certain Tarot cards, for instance).

There are all just my opinions on the matter. Hopefully they serve to enrich the discussion.

I do agree that endgame crafting is expensive, but instead of doubling the amount of ressource we have from dismantling items, i would forsee a way to trade/exchange/convert low tier mats to high tiers one.

In the end it is all about balancing.
