Well, I've been playing B2 for a few hours and it seems to crash less for me. Anything higher than 24 players seems to be a guarantee for a server crash.
Some of the new things are pretty cool, like the HUD icons... I think this is good for teamwork, and now people at least know where the objectives are.
People say movement is faster but I haven't really noticed this tbh. Recoil seems still quite controllable to me, at least the AK-47 (haven't played USMC a lot) It's still very buggy though. The movement is still clunky, and you still get stuck every 10 seconds. The hitboxes are messed up, especially on prone enemies. Sometimes they're impossible to kill. Lots of shots don't register.
I agree that the SVD is bad, what's up with that ridiculous scope view? Spawncamping is still there by the way.
It does seem they're straying away from realism (though they won't admit that of course). I think if they'd focus more on slow tactics and teamwork it would be alot better. The INS team seem to be a bit confused as to which direction they want to take with their mod. Realism, or tactical shooter? Sometimes INS feels more like a deathmatch shooter because on some maps, fighting is only centered around one objective (ie: Baghdad).
I rate it about the same as B1: not worse, but not better either. Will uninstall for now and hope they actually fix bugs and smoothen out gameplay next patch. I still think it has potential but INS is just too clunky at the moment.
