Mondain's Legacy, i tried to break it down by trees, but no luck. and i dont quiet understand the journal method
The journal method that Ghost is decribing is probably the only way you can determine if you can mine something or not. If you get a negative comment about mining in an area, you need to be able to look for that by the text that appears in your journal. So what Ghost describes is great information, but kinda requires a bit of scripting knowledge to figure out. So it's helpful to see what script you are trying to get to work.
As for my question, pre-AOS shards don't even have the journal function. Since you are ML-ish, at least that's available to you. Depending on the script you use, it might be easier or harder. But most all post AOS scripts utilize the journal to determine mining success or failure. If you determine that a spot is not minable, you can just note the location and goto the next spot. If you're script is good enough, it'll remember that information for the next round so you don't have to try in that spot again.
