The is 400 gold and gives 12% attack speed. is 900 gold and gives 30% attack speed these are facts. That gives more of the same stat for the relative same amount of gold is also true. That gives relatively more attack speed then  is also true. does not give more attack speed then for the amount of money you put in. Yet it is more efficient percentage wise because of the cooldown reduction.

It's data without context which I'm against. Currently it's just numbers that are open to interpretation and serve no purpose outside of "am I getting my moneys worth", which is also depending on the situation and champion.
