What's your character agility stats? 32767? I mean, you have maximum stats for each character?
If you have full stats for your chars, can you try to see if a DK with 1000 STR and 500 AGI will make the skill animation work?
If the animation is working with low stats, then the animation visual bug is caused by the Agility Bug.
