Played around for a bit, in general I'm really impressed with the changes, in particular the humiliation animations.
However I still find being stunned just as annoying (now moreso because they inexplicably buffed it so I actually die whilst stunned, not immediately after) and despite all the changes to the FAN being for the better, I seemed to be killed by it more than I was.
Dead ringer seems unnecessary - how do you escape in three seconds when usually they're hunting all over for you? particularly with that decloak sound.
As for the new items, I'm one of the 99.9% of players who still has absolutely nothing, and indeed despite being online as it updated, I had a lecture right after so I didn't have a hope of getting a medal.
The new maps look great though, I haven't played much but I like the CTF critboost simply because the only map anyone ever plays CTF on is 2Fort and that needs all the help it can get to avoid stalemates.
