Man, my impressions of this DLC are so negative. Two of the maps are pretty good, but god, it's the little things that drive me nuts. Like not being able to complete the 'one round' weapon challenges first.
My favorite thing might be the my imagined pitch for Verdun Heights: "What f we took a mechanic all the players complain about, and cover half a map with it." "Brilliant!"
I still have to play around some more, but I don't see how any of the DLC weapons are superior to their predecessors. Which is refreshing since DICE DLC weapons tend to completely outclass the launch ones.
