I think what could be fun is making the scrolls easier to retrieve. They could be housed into mini temples (or even existing buildings that can now be destroyed) in the open who have minimal protection, like 200k on the walls or something. They would be spread around in the dead-ish zones, and also each one would have a specific scroll assigned to it so others can plan where they can interecept and such. Having them in trikeeps most of the time makes them too hard to recap by a small team, and the fact that you can drop them in any of your home keeps makes the run too short and too easy to reinforce.
Think of how much more fun it'd be if we had scrolls fights regularly around a collapsed Brindle church, the Moth Temple, Cloud Ruler temple, etc..
For anyone calling on dynamic populationb caps.. it seems like the most recent patche scales defense ticks with server population. I'm getting insane ticks in Kyne being one of 3 online players on DC just killing about 3 EPs. Like 12k just for killing flaggers.
