Honestly, I think Hurricane is the problem
Previously if you wanted AoE on a kit that didn't have it, you were giving up something for it. Hurricane was a pure attack speed stat-stick, so by buying it you were sacrificing a Crit item, a lifesteal item, a penetration item, or a defensive item. That's a real opportunity cost right there. By making it into an equivalent of Phantom Dancer, suddenly you're sacrificing nothing in its purchase.
I can see three potential options here.
-
Turn it back into a pure attack speed item and improve its magic OnHit damage a bit to better synergize with Wit's, Nashor's, and Rageblade (all items people who used to buy it liked).
would be a fine build. -
Keep the crit, but remove the side bolts completely. Instead, make the item grant some sort of crit interaction with OnHit effects (which would probably mean
gets nerfed some more). -
Just removing the thing from the game. It's causing health issues and drastically warping its worst abusers.
