From what I have seen, people who do the glitch are actually just as capable to do it legit. They just glitch because the option is available... sometimes it just less headache, sometimes it's just fun. But.. same thing with the templar... people walked him off... but after the patch, people just killed him... it was like maybe 10-15 more min. depending on dps... but it didn't stop anyone from completing the VoG.
