regarding the 7th-level unit, it's definitely debatable.
what makes archers weak? their stats are quite good. if you consider the "eyes" skill, the ratio of bonus to attack, defense, and health is quite appealing, and the speed isn't the worst... I like medusas primarily because of their petrification ability, although it doesn't work on everyone or all the time, but when you play against a human, they are wary of attacking them in melee without a good reason.
as for medusas, that's true, but I don't like the "eyes" skill. archers of humans and elves are much more effective, and in general, mages are the best at ranged combat, as they have as many as three archer units!
