I think the only time I've actually asked to cheese something was after I ran the VoG successfully a few times. I had asked for it because we kept having bugs in the atheon fight screw us over. One time he wouldn't teleport 3 people. Another the portals kept taking us back to where we were instead of out to shoot at atheon. etc. Oh and to get an atheon shove done on hard mode. Was pretty sure I was never going to be able to run a legit hard mode with friends so I just hopped on a checkpoint and watched him get shoved.
