warrior- " fainal attack' get crash sometime

Anyone face this crash when active the "final attack' skill, it is frustrating

 

I have a buddy that had the same issue on her crusader.
She would constantly DC until she learned final attack was causing her to crash and stopped using it (I guess).

 

Same, I am cursader when entering a new map and using Fianl attack it would be 100% crashing.
When you using Final attack later in a map, i might be OK
