Would you happen to know if it should be showing more threat, or less?
Last night we were doing curator, and there was a point where i had 200% of the threat of the MT and couldn't get the asshole to hateful bolt me.
Then the next attempt, I only had 90% of his threat and pulled aggro off the MT (and was 2-shotted).

Hateful bolts are not aggro based in that sense. They hit whoever is the highest hitpoints in the raid, that is not the main tank.
