Hmm this doesn't fall under Class/Map feedback... so... here's some game mechanics feedback based on my brief stay in Lockdown.
Can't tell if a bomb is friendly or not.
I would run into a Shivermist, only to discover that I'm completely frozen :D Hahaha... Same goes for bomb fuses, walked into a Nitro thinking the bomber in front of me just dropped it - nope - boom.
Other games have an icon in the middle of the blast radius or a different outline color to let you know if the AoE is friendly or not.
Control Point Change Alert
Taking a cue from BF2 (and I imagine most flag-control FPS). We need a text or speech announcement of control point changes...
We lost Control Point 1
The other team secured Control Point 1
The other team lost Control Point 1
We secured Control Point 5
etc...
That way when something is happening, you know without having to glance at the mini-map or run around continuously.
Freeze Release
I was frozen and a teammate desperately swatted at me with their sword to try to free me as one would in the Clockworks, but it did nothing. Might have been a glitch or is this intentional?
Addendum: I noticed that I could not charge a bomb when in a mist, the status was being reapplied and was interrupting the charge. I thought I was just booching it, but spaghetiman noticed it too, so I know it was not just me.
Weapon Balance
The weapons I played with and died by seemed well balanced. Some things like DA, Polaris and RSS seemed OP at first, but once I quickly figured out their attack pattern weaknesses they were a piece of cake. A lot of people were equipping BTB, but all that lunging is pretty easy to overcome too.
And Shivermist/VT/Stagger... um... don't run into it. /derp
One problem I had with the Sentenza was the hitbox... I have to lead the other player by a tremendous amount to hit, and even then it would usually miss. Made taking down bombers very difficult.
Damage Lag?
Every time I took damage my screen froze for about 1/2 second while it was playing the damage animation. Kinda weird, no idea why. This is the same kind of "lag" I get in the Clockworks at times when the computer is too busy doing something to update the screen. Frequently it would result in getting hit several times while I'm waiting for computer to catch up.
Edit: Played again, this kind of lag seemed much better during the second playthrough.
The lack of indication on the allegiance of bombs is disastrous.
I pretty much agree with all that has been said here, I just didn't experience any lag.
