Pay-to-win ward skins are annoying

I think there should be a universal ward outline when sweeping. You might think I'm stupid and I may be but in this case, I was sure Heimer was a ward since there are wards like the Demacia Vice ward, etc that look identical to a Heimer with his current skin. There is also the Ornn ward which always gives me a mini heart attack because it's literally bigger than Teemo.

Any thoughts or similar experiences?
