Hello,
To download files (profiles/fightclasses) of WRobot for official wow servers you need active WRobot subscription on your WRobot account (no restriction for WRobot files for server private).
Can you check if Wow create crash log file (in folder "C:\Program Files (x86)\World of Warcraft\Errors" by default) (if yes send me txt file by private message)
Hello,
Like:
(ObjectManager.Me.FocusObj.IsValid && ObjectManager.Me.FocusObj.BuffCastedByAll("SPELLNAME").Contains(ObjectManager.Me.Guid))
If you use fightclasses editor, you can convert your xml fightclass to c# to get code sample
