Why does Stinger still exist?

It actually builds into two items. The other one, Dervish Blade, is only on Twisted Treeline.

That said, I'm not sure why Stinger still exists either. As far as SR is concerned, it only builds into Nashor's, and Nashor's happens to be the only on-hit AS item that doesn't build out of Recurve Bow.

Either that or, instead of removing Stinger, have it and Recurve Bow build into a variant of Hurricane that's designed for on-hit effects rather than being a Zeal item. (I mean, Hurricane's passive is a named passive despite it being the only item in the game with that passive...)

Bring Zephyr back, so will build into 2 items again

it used to build into zephyr. we have 0 pure ad attack speed items. they just want that for ad carries. or else buy inefficient shit
