I've seen some things in 1.1 that I haven't seen before. This probably should be posted on the bug report or tech board, but I thought it might be of value to show that something can appear to be cheating.
A few days ago, in a Flak Panzer, I repeatedly hit an enemy tank at between 750 and 1000 yards. I kept shooting hitting him each time for several minutes with no affect. I tried moving my aim point slightly several times to vary where I was hitting him, but no joy. I watched hit sprites constantly flashing the whole time. Sometimes I could see where my shells were bouncing off the tank and hitting the ground nearby, but he would not die or even smoke. He finally located and killed me. To be fair, I have seen FPs get damaged before and seem to become very hard to kill, but they at least smoked.
Yesterday I saw a enemy GV attack a vehicle base. About the time I started shooting at him, he disappeared. I looked all around thinking he may have warped, but he was nowhere in sight. After a couple minutes I started getting hit and saw the enemy GV had reappeared in the same place.
I have also seen many planes dive in and at 2000 yards suddenly warp to 500 yards. The night before last this happened repeatedly at a base being attacked by bish hoards. The net status looked fine but it could well have been caused by Internet problems.
These were seen while in GVs, I haven't had any trouble while flying planes, but I've only been up a few times.
I don't know if the cause was by design, the host or network lag, but it seems to have gotten worse with this update. I've also been getting many dumps to desktop after the 1.11 patch and one complete lockup last night. I can't remember having either happen to me before, so I think there are new issues in this update creating problems that look like cheating.
