It kind of sucks that using the grenade launcher is frowned upon. I just recently figured out how to use it. People kept killing me with it and I couldn't figure out how when they weren't even to the level where you can unlock it. I admit, I use it quite frequently but only because I just figured out how to use it. My preference is still the Strauger UA-1 or the Sniper Rifle depending on the level I'm playing. I apologize if my use of the grenade launcher has upset you or anyone else I've played with.
