I would typically use the first mission on the moon with a wax idol and wake the hive, but there aren't a ton of elites to get the big buck$. I typically don't farm with a team, so strikes are out for me (do you really make considerably more glimmer when in a fireteam?). Exclusion zone is pretty good, but there's a lot of trash to get through (including those annoying shields) before you can get to the elites, but they 'ARE' pretty plentiful on heroic and pretty easy to pop off headshots with. I've heard the gatekeeper is top notch, but I haven't tried that yet. pain to find somebody with the checkpoint. Does it have to be on hard mode?
