IE is counter intuitive as it is now
Assuming you have no other items, combining 2 BF Swords for 1000 gold gets you... an open item slot.
The two passives on IE have zero value until you invest at least 600 gold into critical strike (Brawler's Glove is the cheapest critical item there is). Granted, some champions can bypass this 600g investment with guaranteed critical strikes. At the core, though, IE is poorly designed and now suffers the same problem Essence Reaver had prior to its rework.
So here's what I've come up with:
Infinity Edge
Recipe:
+
+
+ 300g (3500 total)
+80 AD +10% Critical Strike Chance
Unique Passive: Critical Strike chance is multiplied by 1.5 (increased by 50%). Unique Passive: Critical Strikes deal 15% of their total damage as True Damage.
With this change, Infinity Edge remains weaker on its own without a second critical item to increase the use of its passive effects. IE + Zeal upgrade still comes out to 60% critical Strike chance. And, it helps enable double zeal upgrade builds (which would total out to 105%).
Thoughts?
or any magic pen item, because you don't have enough AP to make decent use of them.
