Here is my take on Ravenhill Scout.
Its not really a solo card but can be pretty awesome on multiplayer, especially 3+ with a good spirit deck that can pile progress tokens on locations. In this situation Ravenhill Scout accelerates what Spirit is doing allowing you to get rid of the worst threat locations faster while leaving the lesser threat locations in the staging area.
In solo it can't compare to the Northern Tracker and what Rohan can do. But if you're playing without spirit and want to manipulate locations in the staging are Ravenhill can do something but probably no enough. You need to travel to a location that requires 4+ progress tokens to explore and then quest enough to get 2+ tokens on the location and move them around. Ultimately you'd be better taking more questing power and powering through.
I found Ravenhill really useful in a two player game. I had a lore/leadership deck and the second player had a tactics/leadership deck. I had two Ravenhill and was using them to keep the staging area clear of locations.
So its definately a card that works better in multiplayer in my opinion and its nice to see another sphere other than spirit be able to manipulate progress tokens on locations (OK leadership has Snowborn Scout to.)
