Disagree
IMO :
- Recons are low power units but with good chance to disengage, good vision range, better result with tribal and a litle bonus against animals. Not usefull in a war, unless vision bonus.
- Hunters are low strengh specialized units, mainly against animals, but this knowledge about animals can be used againt mounted units too. Nearly useless in a war, unless ennemies harass with dogs units
- Criminal units are "assassin" or "pirate". Assassin are stealthy low power units (same level as recon) to kill civilians units or perform special mission. Pirate are nearly as strong as military units.
