As for the knockoff from LM, if I feel like I can kill you or the LM is under control I will actually grip you back onto the LM so I can keep you from just going somewhere else. This also depends on your class, I am more likely to do this to mage/priest/pala/rogue, etc. People who can survive the fall. I would rather you sit in the GY waiting to rezz or even fighting outnumbered at LM instead of just moving to BS or something.
So... yeah. Just because you don't understand the use of DG does not make it wrong.
