Umbral glaive is broken in terms of vision control and gives an unfair advantage to some supports

The item doesnt seem broken because it's not a one shot item for carries, but its broken in terms of vision control. Revealing wards and one shooting them with autos (even for ranged, even the ones revealed by sweepers, not even just the item passive) is absolutely crazy. Im a long time enchanter main but I've been playing a lot of senna and pyke (and even ad miss fortune support just to prove a point of how good the item is) and it's just insane how much vision control you get with the item, you can clear one side of river and all its bushes top to bottom with one sweeper. meanwhile as an enchanter you struggle to kill two wards that you revealed and you rely on teammates and ardent to kill more. And dont even get me started on playing a support that cant buy umbral glaive versus an umbral glaive support. Might as well sell the warding item since your wards are completely worthless vs them

It really seems unfair and its just yet another thing in which enchanters were left behind in this bot lane rebalancing. HOWEVER, am I asking for the item to be nerfed? No, it's an amazingly designed item that ad supports need as a strong first option. What I think should happen is other support classes get access to the blackout passive. My suggestion is only for the enchanters blackout item because I dont play enough tank supports to speak for them. Ideally it would build from forbidden idol and a tome, give 10% h/s power, mana regen, very little ap and just the blackout passive. It would still be bad to rush it as opposed to umbral glaive which is a must first buy, but at least we could get it mid game to catch up in vision control.
