Okay most of you probably know this but I'll post this anyway for those who don't.It feels like it's taking eternity for prospecting all your ores / milling your herbs when doing it the usual way , so here's a macro that will help people speed up.
For prospecting :
#showicon Saronite Ore (Or whichever ore you are prospecting)
/cast Prospecting
/use Saronite Ore (Or whichever ore you are to prospect)
For milling :
#showicon Adder's Tongue (or whichever herb you are milling)
/cast Milling
/use Adder's Tongue (Or whichever herb you are to mill)
Turn on Auto-loot and all you need to do is just click on the macro to do the process.
Note : The macro won't work if the first item from your bag is a stack of 1/2/3/4 , you'll need to put that stack as last.The macro will only work if the current stack to be prospected / milled is a number of 5/10/15/20.
Hope it helped somebody.
Regards
