Hey,
I'm creating Fortune Cards all day and I have to mill a lot of plants, and during the process I found a little trick (not an exploit but not a guide either...) for make it slightly faster.
1 - Turn on autoloot (obvious),
2 - Create a macro to mill your plants :
Code:
/cast Milling
/use Plant name
/use 2nd Plant name
/use ...
3 - Open an UI window that won't be closed by the loot window (e.g. Escape menu) <== Here's the trick
4 - Start using your macro
If you don't do the third step, the loot window will display, and it will take a bit more time to collect the result of your milling / prospecting, and it can also sometimes stay stucked on the loot window, like if autoloot was not enabled.
This is really a small time gain, but if you're milling a big amount of plants, you'll definitly save some time.
Hope you enjoyed it ^^
