With focus specc (no unremtting) i have been pulled back "mid-air" plenty of times. Not sure if you got your facts straight, only reason it wouldn't work would be if i was whitebarred or otherwise immune.
that does not matter what spec u are pal unremmiting/unstoppable gives u CC immunity AFTER u landed not mid air
(unless they changed it will check on my jug but i doubt it its 4 secs CC immune since the momment u land), so don`t matter what spec u are, u prob just had lag
Edit: man pls don`t insult me with resolve crap i`m playing since day 3 after launch and THIS did not happen just in 1 wz and i`m like oh i should post a thread to waste my and others time because i THINK THEIR MIGHT be a problem.
