That wonderous sound indicating that your skill wasn't ready. I realised that after the Spunky update it went really low volume, barely noticable over the sound of combat (atleast for me). I want it back and loud!!
I noticed the same thing. It seems Uber tweaked the volume of certain sounds. For instance the "bowling pin" sounds that comes from a Tank making contact with an enemy with Charge 3 seems to be quite a bit louder post Spunky.
All I hear is "derp". How is this on page 2 with nothing but ridiculous responses to Jim asking for a slight tweak?
