Do you guys make Dervish Blade's active offer move speed only for melee champs on purpose?

Mercurial Scimitar was already patched long ago at this point(It's active offers move speed for ranged champs also.), but Dervish Blade is not.

Because it's unavailable at SR, just it's too unconcerned, I think.

And there is no reason not to patch this at all.

If that's not an intentional point, patch this item, pls.
