Ninja Tabi 103.64% gold efficient without its passive XD

Berserkers greaves are like 128% gold efficient.

Most items have a much better gokd efficiency than that.

Is this a bug or intentional?

it's almost as if armor is supposed to counter AD until late game it's balanced becuse your enemy lucian can be killed by your mage

When you have % armour pen it is nowhere near gold effiecent without the passive.
