I’m also a bit disappointed to see the affix go, but I can accept the reasoning.
There’s several reasons I like it instead of just health, but to list the two big ones: making health threshold bonuses safer and more powerful feels very clever, and favouring endurance threshold makes sources of health recovery more effective.
But I think they EHG are right when they say that
And endurance threshold showed up on a lot of different items for all classes, so a lot of players had the experience of finding it, doing the math, finding out they did the math wrong, and then finding out it’s worse for them. Even though there are good niche applications of the stat, it probably isn’t worth having a lot of players stumble into that trap and ultimately come away disappointed.
I’m hoping we see further support for endurance & endurance threshold in the future, but maybe it can’t work as a broadly available stat.
