Suggestion for Sweeping Lens

For pure ward clearing power, Oracle Alteration is always a better option. However, since the Sweeping Lens is a stationary active I think there should be a secondary effect that plays into the counter warding meta game. Basically, make it so a short term (1 min) "ward trap" is placed at the location that you cast. This would act as an invisible version of Cait's trap (so no vision properties) that will activate if a ward is placed anywhere within a small radius of the trap. A notification will be sent to the team that a ward has been placed in the brush and the trap would go away.

That way there will be a meaningful decision when deciding between Oracle or Sweeping. Sweeping gives vision superiority of a single brush, while Oracle gives lesser control of a wider area. This would be interesting choice in my opinion, especially for highly contested brushes.
