Make Youmuu active melee only

Would nerf the item too hard nobody would use it.

I don't really like melee or range only items, however, I could see them making the effect stronger/weaker for melee vs ranged attacks respectively. This would also make it so champions like can't abuse it by swapping combat forms.

Also, this would be a nerf that would allow for some of the base AD to be restored.

I saw yommus more on adcs then melees even before the korean builds.
