Imo it's better for support to start with warding totem, and upon purchasing sightstone change your trinket to sweeper, and leave an empty inventory slot for pinkward to keep with you after every b. Most times around the time you reach "full build" and have tons of excess gold even after buying elixirs your team should have  a couple of members with upgraded vision items and with a little bit of communication this should include 1-3 vision totems (1 is not enough though).
