I don't like the idea of random teleports in the Atheon battle. That said, I would trade higher chances of raid gear drops for random teleports. It's annoying completing the raid with my friends 5 times and only having 1 set of boots, a decent rocket launcher, and a decent scout rifle to show for it. Some of my fireteam members haven't gotten any armor at all. It sucks having to wait a week for the rewards to reset.
