Ohmwrecker- AP Split Push Item

Ohmwrecker + + + 500 Gold = 3400 Gold +90 Ability Power +6% Movement Speed +50 Armor +125% Base Health Regen. UNIQUE Passive- Point Runner: Builds up to +20% Movement Speed over 2 seconds when near turrets, fallen turrets, and Void Gates. Upon killing an enemy tower, gain 100% increased movement speed for 5 seconds, decaying over the duration and being lost upon dealing damage to an enemy champion. Active- Zap Laser: After a 1.5 second delay, the Ohmwrecker zaps the target area, dealing 250 (+25% AP) true damage to all non-champion units and structures. Enemy minions take 25% increased damage. The cool down of this ability is halved if a structure is not damaged and reduced by 2.5 seconds for every enemy minion killed by it. (60 second cool down) (750 range)

Ohmwrecker's tower dive identity is just not something I see ever being useful without being OP since champions that want to tower dive often have mechanics already in their kits that allow them to tower dive and take very small amounts of damage, the outcome hardly ever being made by the tower itself. So, instead, why not change Ohmwrecker to fill in Banner of Command's old purpose of an AP Split Push item? The passive allows you to escape once killing an enemy structure and the active helps with both clearing enemy minion waves and destroying enemy structures. This also provides another AP+Armor item for the Mage arsenal of items.
