Looks like we could use a discussion of these to give feedback before the upcoming changes.
My few thoughts so far:
Adding some more leylines to bashing areas could be an interesting way of getting priority in them for a circle. I think Demon's Pass would see some stronger contestation than it already is if it wasn't Demonic inclined.
It would be interesting to have some connections between leylines, letting you hit the natural influence some if you shift the lines flowing into them.
Keeping them out of shardfall areas seems solid. Stops it from being a togh feedback loop of shards <-> influence
