I'm having a lot of fun, I hated it at first because I thought it was too luck based but I found that it's not that bad, especially once I got some permanent upgrades. However, I do found another thing I want to point out... the reforge mechanic, specifically the comparison part of reforge and the mythic rarity.
First the comparison, I like how you can now, after buying the upgrade, decide whether to keep your old or change to new attribute. What I don't like is how you compare them. You have to pay really close attention to the %s of the attribute because it immediately jumps back to the old attribute. I get that in the long run, getting good attribute that will pay more is better, but I sometimes what the smithing-related attribute like reduced break chance, and accidentally missing it because I wasn't paying attention is annoying. I would love it if you could actually compare the attribute side-by-side so that you don't need to go off memory to decide whether to keep or not.
The 2nd is the time it takes to get mythic rarity. If I have enough cash, it's not a matter of gambling anymore, it's just a matter of time, and it takes way too long to try to get mythic rarity. I almost don't want to get it not because of the low chances, but because it's just so boring waiting for the animation to play and to reforge again. is it possible to change it so that the animation speeds up or something? or maybe have a quick forge where you can decide like "reforge this up to 100 times OR until it becomes mythic rarity" and have it finish reforging until the conditions are met? you could even add conditions like "get this attribute" if you want specific attribute.
Edit: Unrelated to the points I mentioned above, could you also explain what it means by "the market is 25% dearer"? on the Sign of the Hearth description? At first I thought it meant as "25% cheaper" but since every other signs suggest an upside and a downside, it sounds off. then I thought maybe it's more expensive, but then why specifically the word "dearer"? maybe it means 25% less likely to find higher rarity item? I don't know...
