it still wouldn't see play.
it's an item that only works near enemy turrets, and it's a big gold investment of +2500 gold. improving a tower dive isn't even too useful as well. When's the last time you had a bard specifically ult only the turret and then the rest of the team actually capitalizing on that turret-no-shooting time interval and diving? (I'm gonna bet 1 guy out of a hundred who read this is going to reply with their one game example out of a thousand games that they've played where the bard-tower dive actually happened)
You could easily just buy an aegis for 1500, that will serve your team way better for teamfights and tower dive scenarios. Or a ninja tabi, which is 1100 gold, reduces auto damage by 10 12% and actually works on turret autos if you're really deadset on diving.
and the whole "buying an ohmwrecker for tower dives" doesn't even happen because it's too slow; by the time your support has enough gold to buy it and has finished their t3 support item, sightstone and boots, laning phase and towerdives will be a thing of the past.
what Ohmwrecker needs, is a zeke's herald level rework where it just does something else completely different, possibly not even about turrets, that's cool and useful.
