Mikal'b of <Contraband Inc> on Jedi Covenant using a NovaDive: achievement for 6 kill streak. I think I actually killed 8 or 9 in a row that game, but I didn't SS it so I don't have proof. http://i39.tinypic.com/jl7286.jpg
My best damage in a game was 31k, but I didn't screenshot that either so I guess I don't get credit.
EDIT: Here is the achievement for 30k damage, so I can at least say I got that much: http://i44.tinypic.com/1p9fs6.jpg
Also on the NovaDive
Oops just noticed that the leaderboard is only for 50k+ so disregard that damage part.
