How many games have you played where the number of encounters was about six per adventure day?
The "always on" features have staying power.
I've got a DM who tended to offer up deadly + encounters, about 4 per adventure day. In Tier 3 this put a bit of a dent in the HP resources. And it highlighted how you have to be smart with your spell slots and other LR limited resources.
most other games I've played have not quite reached that level of resource management requirements.
For Stoutstein: Yep. (As to AoE).
