Definitely get it, Vic.
Mortars can be a slight annoyance for me.... but I can't say they've ever seriously hampered my game play. They might get me once, but once I see where they're mortaring, I can generally avoid the area... or plant quick and get out in time.
I continued to kick butt tonight. As long as I take it nice and slow, I tend to do well. Sniping is so nice with the bipod now too. There's no scope drift at all when lying down with the bipod deployed which is a huge help. I think I've had the bipod for a while too, I just never put it on for some reason (dumb move). Man, I love this game.
