Whiptail spawns going crazy, I made a post (4.0.6- Herbalism After Hotfix) on my little route that I was making a killing off of. There was a comment that asked about what addon I used to get the "timer" on the spawns. Thanks to our little "Gatherer" addon, I was able to get some extremly accurate information on the spawnrates.
Next, you will need to go to the Minimap on the left side, right below your General options. Here, you will need to click [or check] the "Display nodes on Minimap" option. This will allow you to see nodes all over the place. If you are using the addon and see any glitches upon clicking these, go back into your /say or /chat and use the command /reset. This will reset your UI and will allow you to use full capability.
There are a few other options that you can use, however I prefer to keep the simplicity for only the things that I use, I am sure folks that use this will add in comments if there are other options that they enjoy (and a how-to) in case I missed something.
Now I am guessing that there are some folks that are thinking "It's not worth my time to gather (mine or herb), I make more at the AH". Well, if you enjoy sitting at the auction house all the time and don't get out in the real world, well, that's your perogative. As of late, I am enjoying getting back into the game, and after an hour in Twilight Higlands picking Jasmine and mining Elementium Ore and Pyrite, I hit 2200g (pending auction sales) in 60:02 minutes. Without going into further detail on that (I know, you guys probably miss that), even fighting a drood "bot" (i think at least), I still had no issues hitting the over 2K GPH. =)
