I know it makes sense that you could talk to an allied unit to recruit them, but why exactly do you talk to enemies in the battlefield to recruit them?
Wouldn't it be a little bit more realistic if you just capture them first as prisoners of war before having them defect at your side and use them in the next chapter or something? I know that some playable characters are probably related to those enemy units or some of those enemy units have probably been thrown in the battlefield against their own will, but they still need to lock them up, at least temporarily, just in case they are actually planning to kill the playable Lord or something.
I don't know I just don't understand this. Can you guys tell me why?
