This is quite annoying especially as a tank. Tank being my main spec, I usually fly into Sunsong Ranch to start harvesting my crops. After doing so, I have to kill things. So I go to switch into my DPS spec and everything disappears. So I have to zone out / back in to make everything reappear.
This has been a bug for some time, I figured you guys would eventually fix this. I thought maybe the devs are unaware. Unlikely, but just in case wanted to get the word out.
One request - For the new challenge modes (if/when), give us epic, matching weapons/shields for the current Gold challenge mode gear.
