RP should be an option for reporting on the Support Desk

[Singularity]

"Griefing" is the correct avenue to report him under if he was deliberately screwing up your run by dragging the boss around. There's nothing wrong with RP in-and-of-itself and the fact that he was doing so while screwing up your run is irrelevant to the nature of his offence.

Actually, reading that again, I'm not sure you're aware what the abbreviation "RP" is commonly understood to mean. It typically stands for role-play(ing).
