Other considerations were:
Dwarf: artisan - the defenses begin to stack vs ops in an interesting way. I chose human: artisan because the financial qualities ensure a complete build. This type of complete build enhances the ability to raze enemies by the 2nd to 3rd wave in war, unopposed.
Undead: cleric - this fixes the other half of the racial limits(no hospitals), as the player will simply get use to having a less impactful role attacking. You do bolster the team, so this has sleeper quality.
Elf: mystic - gets chastity back in the game at a reliable clip. I opted to go with dwarf for a mystic with clear sight.
Faery: rogue - plenty of proof, history and effectiveness. I opted against it here because meteors are more problematic for this build than gnome.
PS ~ almost missed human warhorse bonus, so human: raider might be deceptively good. Plus, raider is thief biased so humans synergy remains intact. Because of this kingdoms distribution limits it remains an undead salvation build.
