Not that I really care much and understand the practical reasons, but I got to thinking in beta, why does a mechanical "person" who doesn't breath need the helmet, or even just why for protection when the helmet is the same looking material as their heads. Again, I'm not bitching, I totally get it's just programming continuity across the races, but I do chuckle thinking about the absurdity. Edit: Good catch, smartphone posting and didn't proof read, thanks.
