I got some problem with my aura ennemies buff - When i purge an aura ennemies, its not desappear on the screen. For exemple i purge a shield from a disc priest, it still showing shield but when i look on the guys he don"t have any shield on him.
Sometimes aura buff take some time to appear too, i don"t know why - Before i never get any problem with, maybe i should settings or uninstall réinstall ?

I have the same problem. When I succesfully purge a npc or a enemy player in arena, it takes about a second or so before the corresponding aura on the nameplate disappears.
