Gangplanks "Raise Morale"
Raise Morale Cost: 50/55/60/65/70 Mana Range: 1300 Gangplank fires a shot into the air, increasing nearby allied champions' Attack Damage and Movement Speed. Passive: Gangplank gains 8/10/12/14/16 Attack Damage and 3/4/5/6/7% Movement Speed. Active: Gangplank fires his pistol into the air, disabling his passive boost but increasing his Attack Damage by 12/19/26/33/40 and Movement Speed by 8/11/14/17/20% and nearby allied champions' Attack Damage and Movement Speed by half that amount for 7 seconds.
Other than the Passive Damage and Movement Speed, this ability is seemingly useless. The buff is so small that you might as well just max everything before grabbing this. I don't know how but Riot really needs to edit this ability.
