Why?
It doesn't fit into the context of when it happens.. it's not heroic to just randomly scream/yell/roar when you're just standing around at a bank, that's just crazy, not heroic.
I like the cocky idle pose and the strutting walk, but I can't deal with the random yelling.
I use, assassin on my nightblade and the only thing that really bothers me is that he plays with that damn knife like every 5 seconds, it's almost as bad as the indefinitely barking dogs.
I want a wise/noble kind of personality for my future warden/druid style character, like you'd expect from someone who has the power of nature itself at their fingertips but is humble about it. Thought about commander but it just doesn't fit.
