It would depend on how the nerfs would’ve been done, and if it would’ve been satisfactory. It’s highly possible that any nerf Riot did just made Ezreal rely on double tear to be useful, which wouldn’t feel good either.
It’s reverse of what they did back with Cinderhulk. When Cinderhulk was strong, Riot hit the champs first, then the item, and many of the champs that were nerfed because of it were then terrible since they were double nerfed.
At least with this way, AD Ezreal and AP Ezreal can still function without being forced to build double tear. Plus, Maybe it shows there’s some value on other potential Tear items, like a defensive or a hybrid one, without them all growing stronger off of each other.
