[Batman TAS] Why is the batsuit as such?

Namely, the lack of a covering for the mouth on the cowl. Over the series Batman faces numerous foes who use gases and such, and surely after the first occurrence, the Batsuit would be redesigned to accommodate a rebreather? Or is the BatChin that important?

Batman has to walk a very fine line. On the one hand, it's absolutely paramount that he's a force which criminals respond to with absolute terror, so that he can intimidate. On the other hand, however, he's a vigilante very much devoted to protecting the innocent. Terrifying innocent people works against him, so he shows just enough that people can see he's a person. 

Think of how different a person looks smiling and scowling.
