Probably a troll. There is no way someone could level WHM to 50 and not understand the basics of the job. Even if they levelled purely through PotD and never had to reliably solo heal, they would still know what CS does, or how to target other players properly, or what SoS is.
Even if they were drunk I doubt they would be that terrible.
Though I might be putting too much faith in the intelligence of PUGs again.
