I seem to be getting shot through walls a fair bit by bots that don't have obvious LOS. Can't say I noticed that before 1.2.
There also seem to be a lot more crates around than you'd expect in hardcore, makes it a bit easy. A box that only gave extra clips would be better, so you're stuck with what you find.
Also I feel those suicide bombers really should be on a deadman switch in hardcore and counter attacks should nade before going in if unchallenged. Pointing guns at doors shouldn't be the winning strategy....
Even after my gun loads I'm quite often not getting my scope until the first flag goes.
I can't grab weapons off the floor now, as they won't be ready to use for 3 or 4 minutes.
With the lag/jerkiness (maybe it's some kind of slight rubber-banding) This patch has made it go from running pretty nicely to really horribly for me.
