User blog comment:Mineko Charat Lucky/Ward skins, why doesn't Riot expand on them?/@comment-4361160-20130415125532/@comment-4022742-20130415163209

It doesn't really matter much which is which to the team, for 1 reveals other wards (Kill On Sight) and others don't. What skin they have doesn't make a difference...

And it doesn't really matter which is which to the opposing team for, any ward they can see they will clear anyways.

Your argument is invalid.
