Only 3 of the 4 trinkets seem to ever get used at the end of the game

The warding totem and farsight alteration are both very viable picks with different uses and both get utilised towards the end of games. However, with the red trinkets only the oracle alteration seems to get picked towards the end of the game. And when people buy a sweeping lens it's simply because they're not yet level 9. I think this takes away from the potential choices a sweeper user has. Is there anything that could be changed about the sweeping lens to make it a viable late game pick?
