Go against the Super-Elites, enemy faction doesn't really matter to my knowledge, try to keep up killstreaks, you don't have to have it on Insanity, use at least one to three handicaps, and you should be fine. I can easily get above 10k just off of super-elites, but I run a biotic death squad. --- GT: BigRaff87 | http://24.media.tumblr.com/tumblr_lp6lrnL8em1qgmo67o1_500.png |The Amazing Spiderman of GameFaqs

Shouldn't be very hard even on Insanity as long as you're decent at the game and have upgraded your stuff. I've done the Arena a number of times with different classes and I usually just run the Lancer and then enable No Medigel/Thermal Clips versus Cerberus Super-Elites (ridiculously easy to kill). You can easily break 10k if you're leveled up since everything minus Atlases should die near-instantly, resulting in huge streaks.
