How to rework Ohmwrecker to make it an attractive buy without breaking it...

As the title says...

As is rarely ever bought, I felt like it could use a small rework to make it an attractive buy.

Stats:

-Health: 600

-Armor: 80

-200% base health regeneration

Unique Passive: Point Runner

Unique Active: Enemy turret cast: Prevents the enemy turret from attacking for 12 seconds

Allied turret cast: Makes the turret immune to all damage for 20 seconds, as well as increasing its damage by 150% and creates a small area around the turret that heals all allies, both champions and minions by 50 up to 4 seconds (200 health max)

Both casts have a 120 second cooldown.

Build patch:

+ + 500G = 2400G

By allowing to be cheap, it will be geared mainly to tanks and tank supports (enchanters as well if they want the survivability or the active/passive) that allows them to be viable without being an auto-loss troll pick. It will also make top lane tanks stand a chance against juggernauts and bruisers.

is a champion desperate in need of buffs and I feel like an indirect buff to him will help him slightly and hold him until he gets his nerfs reverted (Unstoppable and his damage returned).
