Let me just start out by saying that I really love the work that has been done on the mod, especially with the Dwarf factions.
It does kind of bother me that (in a future date when the Elves are released) the entire Fellowship may be summoned, all nine Ringwraiths...and only eight members of the Company permanently? (Dwalin, Balin, Thorin, Kili, Fili, Bofur, Bilbo and, if another Dwarf player/AI is on the map as Erebor, old Gloin). I guess the main reason would be that it would be difficult to create unique quotes and abilities for six more Dwarf heroes.
I wonder if there would be any way of implementing all the members of the Company as permanent summons, the same way Kili and Fili are with Thorin. Make them penultimate abilities (unlocked at lvls 7, 8 or 9).
