Back to the Ward Bag

It appears that with the trinkets and the sightstone in game the support has once again been relegated to being a bag of wards. Any support worth their salt will buy a sightstone and get a pink trinket (or a sweeper). In the lower rankings (Bronze, Silver, Gold) this creates a disincentive for other lanes to 1. upgrade trinkets and 2. buy pinks. I thought with the restriction to 3 wards each this wouldn't happen. But with the Pink ward not taking up one of those slots many low ranking players believe that 4 wards on the map is sufficient, or that they are not responsible for vision as the support has 4 wards...HELP! Spending minutes in game attempting to convince players that more than 4 wards is really good gets very frustrating. Alright, sorry for the whining, just needed to get that off my chest and into the discussion.
