Is there any map mods

[Verpin]

that will show all herbs/mining on the map without being near them?

[Unholy[S]haman]

Aye, Cartographer, Metamap etc. But those you have to actually visit the locations first, or, import someone elses saved variables.

[Verpin]

Yeah I want one that doesn't require you to go to them first

thats called a map hack, well a variation of the known one, basically if you were to have that it would have to load the entire world to find those herbs (or the entire zone) and your comp would either lag or crash because it cant load it all at once, imagine having orgrimmar loaded with the rest of durotar (imagine the lag from the lowbie's) you probably wouldnt be able to see your character move your comp is processing so much.
