I love the fact that the morphs make a sound and would hate to see that removed. (Though a /howl would be funny )
Ran a mission as wolf and sound was not a major issue. It was a low growl/snore and only when standing still. Not sure what "barking" for attacks people are talking about since I still had the usuall pewpew of guns. Does it make a difference for sound which morph version you are running, or what weapon you are using?
