Once, I was playing Lucian with two of my friends (One of whom is a lvl 5 Lucian), when they saw my build, they freaked out because they saw Essence Reaver on Lucian and told me Essence Reaver wasn't a good item on Lucian. Can anyone care to explain?
is pretty much core on inexperienced Lucians. That and another crit item and you have lower cdr, the ability to gain mana from autos and so on.
People just expect the 
+ 
combo because it's the OP build from Korea, so they get pissed if you're not playing those.
Essence Reaver is fine, it's just not the common build as the common build runs ghost blade and black cleaver, but is focused more towards the earlier stages of the game, where essence reaver is focused towards mid and late game.
the only downside is it's expensive. it depends on your other items/playstyle if it's worth or not.
Essence reaver is great on Lucian. Your friends are probably just the kind of people who think ''If Koreans don't build it it must be garbage'' The Youmuus BC build got nerfed :^) Both are great choices.
They're just bad. Essence Reaver provides CDR, which is essential for ability/passive chaining.
Get new friends. Your current ones are just one of those "Korean Wanna-be".
Black cleaver yommu on lucian.
It's not bad. That was the norm before the armor pen build.
