As far the early game goes it would be a straight nerf to the originaly sightstone user. On their first back (generaly level) supports will now be able to to buy the first upgrade what would give them a sort of weaker version of the tier 2 yellow trinket. So on level 5 despite you get this sightstone early you will not get as nearly as many wards you had before. Additionaly with only that many space taken it give a opening to get another pink with you in the battlefield. Overal without a set of other wards you won't be able to get the same deep wards in their enemy jungle on that point.

Ones you hit 6 and you generaly want to upgrade your sightstone upgrade you came to a point where you have more freedom a far it goes what you are going todo in this game. You have more option when comes to a suitable trinket and what support items you are going to get.
