I don't like the killcam, it makes the game look amateurish, also it stops the video for a few seconds, during that time I want to see the action immediately after my death, not a freezeframe of the guy who killed me. Also what's with the thing asking you to take a screenshot on the killcam? Who would ever want to save a picture of some guy who killed them? Pointless.
Everything else though I'm liking, achievements and stats are always a good thing.
I'm also happy to report that bots now actually work on cs_militia. I don't know if this happened in the update, or whether it was fixed earlier (haven't played in a while).
