Played some of the experimental, for the most part positive changes, although the lag and desync on one of the UK servers I played on in the afternoon was much worse than I've had before. Hopefully just a dodgy server and not the result of the changes they've made.
I've found one of the new weapons, the CR75 9mm pistol (CZ75 IRL), very nice from what I've seen/used of it.
That being said, the SKS has the same painted bug as the Mosin did, once painted you can only chamber one round. Would be funny if it wasn't so tragic, they've managed to recreate the same bug they fixed weeks ago with the exact same cause! So yes, don't paint the SKS until its fixed.
