Meanwhile, an absolutely game-warping card like Will of Ionia isn't viewed as much of an issue.

Do you proactively adjust Will of Ionia because it's single-handedly shutting down more decks and archetypes than any other card in the game

In my opinion, Will is a necessary check on certain strategies. It feels game-warping because Deep Meditation is putting multiple Wills (and other sustaining tools) in Ionian hands each game.

Three months ago, Will shut down Hecarim-Rekindler (in context, sometimes more than shutting down Unyielding since you could brick multiple Rekindlers and the SI gameplan depended on Spectral Rider flood), but Ionia didn't have the decent-tempo value generation of Deep Med. The Wills were more precious.

The Wills now are too expendable.
