How is this balanced?

Garen: Rank 1 CD: 160 seconds Range: 400 Max Targets Affected: 1 Damage: 175 + 1 per 3.5 health missing Max Damage: 460 (assuming the target is missing 1000 health and still alive)

Yasuo: Rank 1: CD: 80 seconds Range: 1,200 Max Targets Affected: 5 Damage: 200 + 1.5 Bonus AD Max Damage: 1,000 + 1.5 Bonus AD Additional Effect: 50% bonus armor pen for 15 seconds

How is this fair and balanced? Yasuo gets a cooldown with considerably longer range, does more base damage, gives him an attack steroid for 15 seconds, AND has half the cooldown that Garen has.
