A handful of us donated to Whoknowsit to so he could buy ALL the upgraded guides for MoP for all of us. That was an investment into THIS community not into torrents or into any other. We want it to remain safe for us to continue to use. Whoknowsit is smart enough to know what to look for to take out Zygors' tracking info, but he knows he is NOT perfect. That is why he is STILL careful.
But the thing about the waypoint is that it’s not always accurate. It happened when I was carrying out the Inoculation quest in which I had to kill infected owlkins and collect the emitter spare parts from the crashed ship in the Nestlewood Thicket and Nestlewood Hills. After I managed to kill owlkins, there was a particular spot in the area where the arrow turned green, telling me that a spare part was right there.
I only subscribed about 2 days ago after coming back to WoW after 6 years. The game has changed so much since I left right around the Cata release. I decided to start fresh on a new server. I still had all my old links and logins to places like Curse, WowInterface, etc. Loaded up all the addons I had favorited years ago (of the maybe 1/3rd that were still maintained). Got to level 20 in a few hours of playing. Had to look a bunch of stuff up.
