I have done a 1764 Inner Beast on WAR in 2.3, full STR/Det gear w/Berkserk and X Pot of STR up.

The highest Rage of Halone I think I've done is 1123? or so. Same exact gear as what I used on WAR minus the weapon swaps ofc. Sword Oath/Xpot up too but I don't really do that much on PLD as its too difficult for anyone to actually tank unless the healers are fine healing a PLD with 6000 HP. So it probably possible to hit higher than that, especially with 2.4 gear
