I realize it isn't era accurate but I would like to see non-human NPC's available for hire. Just an idea, probably not on anyone's top ten lists but just a crazy notion. Or maybe expanding the type of creatures available for summons.
I wouldn't mind seeing RP orcs being able to hire some regular orc mercenaries who would then follow them and take basic commands. It would make setting up some ambushes much easier and more fun.
My thoughts exactly, wouldn't hurt to have skeletons or other type of undead available in the summons menu too just to add a little necromantic flavor.
