Also, as long as we're on the topic of Bloodrazor vs BotRK for assassins, even though i personally don't think they should be compared, BotRK fits them so much better than the Bloodrazor. Whats the idea of an assassin? Wouldn't most people agree it's to do the most damage to someone, as fast as possible, one shot them before they can take you out, then either get out or die? If you look at just passive effects, yes, bloodrazor wins, it does % max health rather than % physical, and lets not get into the fact that it did magic damage so it didn't even scale with your Armor pen. But then you take the active of BotRK into account, and it's an assassins wet dream. 15% of their max health instantly, you gain that life back, and you steal movement speed from them, making it that much harder for them to get away from you. Your supposed to be killing them instantly, in a big burst, why are you worried about your sustained DPS? An assassin with really strong sustained DPS wouldn't make sense.

With that in mind, Shaco can very easily one shot a carry late game(even though you should be avoiding teamfights when possible and just splitpushing your ass off), with an Infinity Edge, Statikk Shiv, BotRK active, and Hydra active. And then gets a free gtfo card with his deceive.
