Ohmwrecker Rework Idea

I was playing today and after 3 years I realised that Ohmwrecker exists, I didn't have an idea about what it does and i bought it. Then, after I used it I realised it's useless and that's why no one buys it so I have an idea about a mini rework. I don't know what roles should build Ohmwrecker so i think about support enchanters*? And I think it would be pretty good to be build from and SO: Ohmwrecker - 2300g Stats: +300 Mana +45 Armor +20% CDR Unique Pasive: After using any ability you gain +1% Mana Regen (Max. 150%) Unique Pasive: +10% Heal and Shield Power Unique Pasive: Builds up to +25% Out of combat Movement speed over 1,75 seconds while near turrets (fallen) and Void Gates Unique Active: Prevents nearby enemy turrets from attacking for 3.5 seconds ( 115 Seconds Cooldown).
