I understand animation lag and server latency.
I still don't think where the character in the video stood is a safe place to stand by any means. I have never (under any condition) not been hit in that area. The damage seems to be all the way to the very, very, very edge of those animations, so only the slightly larger cracks seem safe to stand in to me.
Where your teammates are standing (and where they run through) is safe. You should have aimed for there. You would have made it, in my opinion. It's sad the animation is so misleading as to where the damage will hit and also the lag can be quite unbearable (especially after Hellfire).
