Rock, the giant hammer wielding warrior
Because the game needs a big stereotypical barbarian that uses a weapon that's not an axe.
Passive- Adaptive > Barbarians are tough, and can rough it in almost any situation. Any time he receives an attack from a champion he has a chance to permanently gain a small resistance to it. (i.e. 5% chance to increase armor or mr by 1 or 2 depending on the source) Q- SWING > He swings his hammer in front of him in the direction of the mouse. Enemies hit are knocked in the direction the hammer is moving. W- CRUSH > He smashes the ground, doing damage and slowing enemies in the AoE. Enemies in the center of the AoE are stunned. E- BATTLE CRY > He screams with barbarian rage, slightly increasing damage, armor pen, and armor to himself and near by allies. If no allies are near by, the effects increase by 50% (or w/e you think is balanced). R- SLAM! > He plants his feet, lifts his hammer, then slams it down, dealing damage in a moderate AoE, knocking enemies to the outside, and stunning them for a brief period. Enemies in the center take extra true damage. He is immune to stuns and knock backs while winding up.
Just bored. tried to balance skills for a top lane primary. A champ that can lane decently, and rewards good teamwork. Totes a late game champ. All we want is a dude with a giant hammer, and No Jayce doesn't count.
