Yeah, the bomb blast radius is ridiculous.
I was just in single player testing some things with my sound. I noticed that missile tracks seem to work better. The missile tracking seemed more realistic with better hits. I wonder if in their testing, DICE had people either playing single player or on a fast LAN that made lag effects on missile tracking unnoticeable. I wonder if they didn't take lag into account for missile targeting.
Yeah... one of the "enhancements" was to make the stinger more effective... whooooo pee! (/sarcasm on)
It still takes 2 rounds from a 105 mm tank gun to take out a chopper. That much armor wouldn't be able to get 10 ft off the ground!
