What if a guild or religion can have their very own recruitment center that only those a part of the guild or religion could recruit from even if from a different realm. Recruitment costs would be the same, and chance of stats for the recruitment are the same odds. Supply would still be limited. Maybe they could only be recruited from a guild center, or not. Maybe you could donate men to the guild center for them to be trained into the knights of the guild. Could add some role play if a religion had their own troops, or if a trade guild had caravan guards.
