"Ezreal is still going to rush TF and his other big AD luxury item will still be IE since Q applies crits" -> it does not!

One of the main reasons why ez doesn't scale into late... IE gives ez stronger AA thats all. It procs on hit effects and lifesteal.

Well TriForce is one Item for ADC-Caster. It gives just enough mana and an amazing dmg boost, if your spell applies on hit effects or you wave your spells (AA > spell > AA > spell...)

But TF lacks AD. So champions with high AD-scalings and long cooldowns would like another item.
