I'm running one of the pathlines just to see how it plays out. I think there is a couple of things you should change about how they work.

First is have it suggest enhancements. As a long time player I know what ones I need, but a new play might not. if there building something that has prerquecs for it the may end up having to redo henhancments.

Second would be to look at the race. I'm testing with a dwarven war priest. At level six the path wants me to take exotic weapon khophes. As a dwarf a better choice would be Dwarven war axe. maybe a list of feats. say level 6 you pick a exotic weapon and list them.

Just some thoughts.
