This may already be the case, but I would suggest, to counter the loss of Arcane Eye, that Scrying be upgraded so that you can scry upon saved teleport/whispering wind destinations.
Maybe that could be a replacement for Arcane Eye, if it's easy to implement? No focus needed, but your scrying is locked down to those locations?
As a replacement spell for Arcane Eye it might work. Unless it is -added- to scrying itself without removing the current abilities it is just another nerf to the school.
If it gets any upgrade, I guess GSF Divination should be a need to have access to it.
