Well i been leveling miner and i find the mini game quite relaxing and the exp per try is good enough, besides you can sell all that stuff you get, so in short is fine by me like it is, crafters should have a little tweaking especially for those r50 already, if you want to craft items to sell, you should be able to do several at once and please make the quality issue more understandable and less random, if i craft 1 thing with a +1 why the next item cant be +1 if i use the same items?

They should make things easier like if you're r40 and the craft is r20 you should be able to get at least a +1 item evrytime you craft and more possibilities to get a +3 because you're way more skilled than what the recipe needs. And if you're doing a craft of your same level if you use quality materials you should be able to get a +1 item and in some cases a +3 items
