With yellow trinket upgrade, you can already place your 3 wards. With a full build you can't place pink wards anymore, but at what point of the game is your inventary full? Does your team really needs more pink wards then the one your support sets and the leftover wards from mid/late game in the supper late game? game > 40 min.

I like that vision is gated, because with less vision, you need to rely more on your knowledge about paths and things your enemy could de or where he could be. To much vision decreases the risk of many things especialy for the winning team.
