I loved the update. I have already unlocked all 3 weapons and I love all o them.
Sure Natasha isnt as good as it might have been but it has such an awesome sound

. I use sandwich, i love it and its so funny, i never used shotty anyway

I liked KGB but i think that they are WAY oversized.
now about the maps:
Well, not much to say about steel, it practicaly didnt change.
I liked Badwater, its pretty fun.
About Arena: thank god it didnt turn out to be CS:S convertion... I loved all maps,especialy lumberyard an ravin, but when server started crashing on badlands and we had to play it over and over and over and over and over again for many hours, i was realy pissed off
I especialy like how they encouraged people to use krietzkrieg now that he charges up not 10, but 25% faster. And I like the new Backburner sound.
Basicaly, the update was great. I liked almost everything
