Wondering what steel, ore, copper ect is considered rare or good to mine? Still new to all this coming from master BH and have heard of certain resources like diatium (at least on azari) being rare or hard to find. Is there certain stuff that can only be used in certain weapons and armor that I or others should be on the lookout for? Any knowledge some you old schoolers might be able to enlighten me on would be very welcome. Thanls ahead of time.

I would post this on your server board because some resources on my server never spawn on yours and vice versa. Dit for example seems to spawn on bloodfin at an ok rate and for DEs we only need a small amount.
