It depends on the maps, really.

Lego Mafia for instance, everyone stays in their spawn for the first few seconds on certain guns to get a kill across the map. I wouldn't make such a big deal about things like that...and i would hope people aren't.

Guys, if it's not impeding the progress of the game..then why does it matter? There is a difference between trying to get a scout kill and staying behind a box while crouched to stay hidden. Two completely different things.
