Things I've noticed last night.
While you're getting hit with gun fire seams you get pushed/kicked more than in etpub. If you are near a wall or such you can't move away from it, you get pinned.
Panza you pull the trigger there is about a 3 or 4 second delay before the whined up sound begins, ultimately takes about 6 to 8 seconds to fire. Deff not like etpub.
After spotting a landmine it takes about 5 seconds before your team is notified it was spotted.
When in a gun fight strafing left and right seams a little sluggish especially if you get hit a couple times.
Would be nice to be able to throw nades and knifes out of water like in etpub (venice).
These are the main things I've noticed, I don't play the panza arena map don't like it so I'm not sure about gravity and such.
Seams the creators of silent have taken it apon themselves to make changes as they see fit rather than leaving them the way they were or making them configurable and letting the people using the mod configure things the way we want (etpub style). You would think they (silent team) would ask the people who play it their opinion before making such changes or a possible poll or thread discussion.
Hit boxes are very different as mentioned, I've snuck up behind someone put my crosshair right on the persons head and have not got a head shot (or the kill at times) sometimes that person turns and is able to kill me rather than the other way around, which kinda don't make sence to me where I had the jump on them. Seams some guys have adapted to it better than others, although game play seams smoother it's going to take some time getting use to these changes and can be frustrating at times.
