Razor Sharp Buff Suggestion (Poll Inside)

What do you guys think about the Razor Sharp buff only revealing stealthed wards? Reason why I suggest this is that the buff feels like a waste when you walk by a pink ward and it consumes the buff when you can already see that ward yourself. Do you guys think this would be too powerful and that it needs to have a drawback or do you guys think that this would weaken the buff because it can be easy to walk by a pink ward without noticing it? Any feedback is appreciated. Thanks!
