It's more about the CDR really : options to get this stat are very limited on ADCs, and yet some of them benefit greatly from it (Ez and Sivir are good examples, because the more CDR they have, the higher the DPS, espescially for Sivir when CDR translates directly to bonus AS via her ult's passive). The problem of getting CDR though, is that you need some way of fueling the spam it allows you to do, and here the passive of ER comes in handy.

All of that being said, I still think BT is still slightly more cost efficient, due to the extra defense and sustain it provides, assuming you have the shield up when you need it.

A good way of making ER viable on a larger amount of champion would be changing th epassive so it procs off both AAs and physical spell damage. Talon, Panth, and urgot would be happy.
