I like the 20% cdr but I think it isn't a good idea to rush it. While I did win the games where I tried so, that was for a large part thanks to my team. I think it's better to buy Hydra first and then (preferably in a short time to surprise opponents) buy cdr boots and black cleaver, whereas the old build would've been a last whisper.

On it not replacing last whisper: It's nearly as good at max stacks, 30% instead of 35%. Against squishy champions, you don't need the penetration, so it doesn't matter which one you have, only how much AD you have. Against tanky champions, you're going to get more than 3 abilities and 3 autoattacks down anyways, because at that point the fight only just begun. Therefore, it's basically the same as last whisper.
