if the names were above the player's head than it would make tc:e's interface design look something like this game:
wait for the commercial "Lost Planet":

as you can see it doesnt limit your vision at all, the text/font/size looks perfect in that game i showed,
i think names above the player's head gives you that... i dont know an appropriate term for this but it gives you that "real online" feel, i think its cool but its just a personal taste though,
but afcourse... there should be an option where you can change the naming system's setting, like making the names appear only if you mouse over a player, or an option where you can get rid of the names on your display,
but i personally dont mind names above the player's head.
