"And wasting gold? Didn't you read that " Spellbreaker is gold efficient even without its passives"?"

...which is all well and good but you can still get more for your gold for 2800 than 40 AD, 25MR and 20% crit chance.

Gold efficiency is kind of a gimped way of looking at how good an item is anyway because according to gold efficiency alone, Mana Manipulator is way OP as an incredibly cheap and gold efficient item. Do you see every support rushing to buy it every game though? No, they... get items according to the needs of their team, not just the ones that are most gold efficient. Similarly unless you needed the specific combination of AD, crit chance and MR in the amounts given by Spellbreaker, you're better off spending your gold on items you need more, regardless of whether or not it's "gold efficient" (because let's face it, very few items aren't gold efficient).

The best example I can think of here is that Athene's Unholy Grail is gold-efficient without its passive or mana regen bonus but you wouldn't get it on a manaless champ just because of that, would you?
