The knock down idea is probably the best I have heard so far; it keeps the grenades usefulness as crowd control, and weakens them to other attacks. As it stands, I can get about 7 kills per grenade, thus 42 kills per grenade slot. Interestingly, with 2 bag of arrows, a Mercenary archer, and a mourn bow, I can get about 70 kills. For that many slots of grenades, you get 126 kills. A bit unbalanced, if you ask me. Besides which, the bow becomes unreliable, accuracy wise, at too short a range to make it useful for sniping, even with MA. In addition, as Blood and steel is specifically not supposed to be heroic, it wouldn't be appropriate for soldiers to use weaker weapons than the player does.
