meh it depends on the game/what class you are (if any) and what kind of gun you are using.
i will say, if you're in tf2 as a sniper with the machina charged up waiting for something to come around the corner and bodyshot them in the toe or something, then yeah, you're being a bit of a ****, but nothing absolutely horrible.
still, as a sniper with a sniping weapon, in games you should always strive for the headshots, it's generally what get's the job done better and/or the intimidation factor it involves (if you drop an entire team in tf2 with pure headshots in a row, they are probably going to not charge/use that path again, so your teammates can flank them in other spots or bumrush forward.)
whatever floats your boat for the most part, the only time i ever get remotely peeved is when someone talks trash while bodyshotting with the piss rifle, you just look like a harley doucher and you're going to be trolled on for the rest of the match.
