Honestly I don't see the reason for a cap at all anymore. Let it scale all the way up to capped enmity. It would be a huge incentive for a pld to actually actively get and keep hate and would also serve as an indicator of approximately how much they have at the time. And let's face it even if they were doing 5k atonements they still wouldn't be parsing high lol.

Also since it counts as breath dmg (reduced by bdt gear and all those nms with bdt which was a lot post aht urghan) make it so the current +breath dmg equipment works with it and add more so plds can actually boost it with more than empyrean weapon or NNI body
