Gold income items

Make gold income items give the maximum amount of gold on tier 1 not tier 2 and scale the gold income down accordingly (so on average the total income stays the same).

Right now supports are forced to rush the second tier gold income item if they don't want to lose a considerable amount of gold. Very often though I feel like I need boots or a bit of armor instead to deal with some bot lanes. Especially when you're losing the lane, the support has little room to adapt very early on unless they suffer a gold disadvantage (compared to the enemy support).

With this proposal supports won't have to rush the 2nd tier income item and when compared to the current system, the gold income will shift a bit more to the early game while losing some gold mid to late game.

Ideally this will give sups some more possibilities to adjust their builds to the situation early on.

Any ideas to flesh out this simple proposal? Any reasons why this would or would not work?
