I actually like them. They can provide some lulz at times when you get an achievement for something you didn't know there was an achievement for.
I was playing Operation Flashpoint 2: Dragon Rising on Multiplayer and was in a gunship raining hell and rockets down on people. I start taking fire from an APC loaded with people up on a hill, so I decide to charge them. Just as I was about to get a nice shot on them with my rockets and he gets a nice shot at my rotor shaft, disintegrating the blades. So I watch as start to drop. Well apparently luck just so had it to where I crash landed right onto his APC, destroying it and killing everyone inside (8 or so people I think).
So then I hear the Trophy chime and see that I have been given a silver trophy called "The Sky is Falling!", with the requirements that I get a kill with my chopper without the use its weapons.
I lol'd.
