Your condition is no longer obvious to others unless you are significantly injured if you are successfully disguised with a shroud. Who can tell all these Mixers apart anyway?
As (some?) disguises are no longer allowing the person in disguise to be targeted by their usual aliases, this might help mitigate targeting issues in large rooms / brawls.e.g. you type 'attack 1st mona' but at that moment the neon green mona's disguise slips and you attack your mona friend in the bright pink disguise. Just as an example of any number of situations where this might be relevant.
