When I asked people why they use a fake name, a few reasons were named: one is that sometimes you're tired and don't wanna say hello, another is that people react differently whether they face a good player or a noob.
I believe the later is a normal behaviour, though in war times, you have no idea who you're facing.
This is why I'd like the name overlay to be disabled on ennemies (it should remain on frozen bodies and team mates, as in war time, u know who u fragged (thanks to the ID every military man wears) and u also know who your team mates are).
Of course, if it could be a server-side eFreeze option, it would even be better.
