Dont know if its really good... Personally, I get around 5k iron before I can get 1k copper, and maybe 500 bronze for 1k copper... I imagine to get up to fire ect... I will have to use all the previous ingot type, leaving me whit nearly anything to craft armor ect... (well, I just started couple days ago so Im not too sure what are the % drop of the higher ore)
Just the opinion of a new player
not really, the better the pickaxe is, the longer u can use it before it break. For example with a fire pickaxe I can mine for like 12 hours untill it will get destroyed. So it's fine..
