I had probably my best match ever (beta included). It was on the Hoth Walker Assault map, on the Imperial side, and I had 38 kills and 8 or 9 deaths. Until the last minute, it looked like I was going to finish the map with the most kills and most points, but a teammate over took me and a opponent on the other team did as well. We actually ended up losing, though.
Also, on a side note, I just wanted to say this: I understand where the detractors for the game are coming from, where they complain about a lack of content (I personally am quite satisfied), however, with all the problems AAA games seem to have today, content means nothing if you don't have a solid basis for a game in place. And that's what DICE has done. They created easily one of the best looking games of this generation all while having a solid framerate. To me, that's the hard stuff (at least it seems that way). Once Battlefront 2 comes out (and surely it will), they can focus on adding more content (and maybe a story mode). Though, we still don't know what content is coming via the Season Pass for BF1.
