We where taking down Crota on hard, we had the were on the final sword, Crota goes down and goes enraged as usual. He gets up and my team takes him down once more. I lay into him with the sword, his health is at around 0.5% I hit the final slam, and the sword disappears mid swing. Everyone though we got it, we all die and no rewards. Why in the f**king work would Crota be allowed to have 1% health of not more like 0.5%???? I'm pretty sure if you could flick Crota for 1 damage he would have died.
