I'm baffled that it took this long for enmity changes. I'm glad it's here, sure, but this would have been realllly helpful back in like 4.0 launch...

Anyway, Plenary indulgence changes is the best thing here. We'll probably see a lot more 3 stack uses from this. Again, something that should have been implemented loong time ago.
Assize changes, while nice, is the definition of a bone being thrown. It solves nothing, but it's nice regardless.
