Yo,

Since vanilla animations suck balls anyone knows which look properly when fighting ?

Cheers,

You're right, they do look awful - one of the many reasons I prefer NWN1.

NWN2 doesn't have the dance of death, and cleaves aren't even animated.

NWN1 even has this:

So yeah, guess I'd be interested in answers to your question, too.
