Really surprised to not be able to find a mod that fills this niche. I'm playing a campaign as dwarfs and I'm really tired of all my heroes being rank 2 or 3 unless I dedicate an entire province to recruiting that specific hero type. The artillery build line already gives a factionwide +1 lord recruit rank effect at its highest level so I don't see why heroes shouldn't get the same benefit. Making the +1 hero recruit rank a factionwide effect would be a real QoL improvement and nothing OP.
