Maybe I haven't noticed this glitch because whenever I do hunts, I always try being the main tank. I know this is gonna sound silly, but I like the idea of knowing everyone else doing the hunt is seeing that the very big monster is focused on me.

So during hunts, as soon as someone pulls, I use Onslaught to get in there and go ham with Butcher's Block, so perhaps that's why I was always on the enmity list and never had problems with Infuriate.
