Such is the case with Star Wars: The Old Republic's latest glitch, where players busting a groove actually affects combat. According to several sources that confirmed this, by typing /getdown during combat (a dance move) enemies attacking you will be continually interrupted -- including bosses. Perhaps the bad guys were so amazed that players could do the moonwalk that they become stunned out of awe?
If you're hoping to wield your incredible dance powers for either the light or dark side of the Force, know that BioWare is fully aware of this exploit. Considering that the studio removed all mentions of the bug on the forums, we can assume that a fix is coming to the game sooner rather than later.
[Thanks to Kaizlu for the tip!]
[UPDATE: The Reverend Shaw Moore has arrived in SWTOR and accounts are being banned for getting down. Accounts taking advantage of this bug are being sanctioned with the explanation that the offending characters "participated in abusing game mechanics to prevent enemy NPCs from targeting the user", and that "dancing is currently not permitted outside of special Dance Zones."]
[UPDATE #2: BioWare sent us a note saying that the previous update was based on a troll posting to Reddit and that this is a "fake ban email."]
