The grenades are annoying, but if you don't go on a map that's too large and you do a Hardcore server it isn't a huge deal, you get used to them. I only use flashes and an MP5 on Shipment and I usually get a 2-1 Kill-Death Ratio. It's actually my favorite map, if I could find a Shipment map with either FF on or no grenades I would spend all day there. Perhaps I'll check the custom maps to see if there is a server like that.
