Suggestion Medusa Hero

Why is there no 2nd hero skill for Medusa hero, it only has passive aoe slow. Since most of the heroes have a 2nd skill that unlocks on lvl11, I would recommend all heroes have 2nd skills. Also, it should be written in tooltip, like the paladin hero, who has heal spell (I know he have 2nd skill from start).

edit: I think Medusa Hero (50% slow) is one of the weaker heroes

edit2: There is a second skill for Medusa, it just doesnt show up if you selected the unit. Skill: Sphere (+6 armor).
