Lifesteal is there because ADCs need it at some point in the game - but it could still be kept as a situational toggle in the final item. If having a bit less than 80 AD isn't that much of a problem, I can try making a small mana-restore item that builds into Reaver. I'd still keep Brutalizer as the other component though, remember it's mainly thought for ADC casters. I'm among the ones that would like another item to be built from Phage, but they could just remove Mallet to add Entropy IMO.
