Mobius, by your thinking...
Since most people breathe through their nose:
- Breathing through the nose is unoriginal
- Breathing should not be done through the nose
- People should think of different ways (such as cutting holes into their trachea to breathe) so that they are different.

Nice logic there.
The fact that something is overused shouldn't be an argument for why it shouldn't be used further.
Especially in this case, where the usage is likely the most effective usage, and the common response is the most efficient as well.
If it were something nonsensical, I would understand, but something equating to telling people not to breathe through their nose because everyone else does it and that people should be 'different' is just strange.
I believe that we should promote originality in campaign writing, but should not invalidate the 'overused' usage of certain elements. After all, there can only be so much variation that still makes sense.
