Now I'm not talking about losing focus in my mind, losing track of something. I literally lost my focus bar, and so did my friend.
We were in Isle of Conquest, randomly shooting folk up, when suddenly we couldn't use any abilities. Zareall even had his abilities stripped from his bars. Anyone else experienced this? Relogging, reloading, full game restart don't seem to fix it. Disabled addons, deleted wtf, cache and interface. Zareall isn't even running any addons. At the end of the day, only contacting a GM had it resolved.
Apparently Blizzard are working on a fix so it doesn't happen anymore, but until that time anyone who this happens to has to ticket a GM. Crazy how a bug like this can even appear out of thin air.
