Though, to be honest, I'm more bothered by the tube near their eye. Who would design a helmet with a tube near the eye? Especially if you are going to wear it in a place were you will have to shoot and be shot at?

That's not meant to be a rhetorical question, even though we do know the answer: 343's designers!

Its as if 343 can't drop their mistakes. It looks as if someone has tried to mitigate the suck by altering the tube to make it obstruct vision less. What they should have done was remove it completely. That decision would have saved time and polygons and would have been an instant win.
