I've just completed all the kits achivements for both solo and team Lucky Island. I've noticed that every kit got something useful, one is stronger than the other. But the villager kit (2x Villager Spawn Egg and 16x Emerald) is pretty much useless. The trades you get with a villager are for example to get Emeralds instead of Emeralds trading to an item.In the case of the Librarian Villager, he gives you the option to trade a book and some Emeralds for an enchanted book. But it's hard to even craft a book in Lucky Island and even if you craft a book and traded it for an enchanted book you still need an anvil to put it on your gear or weapon. So lets say you're Lucky and got a Villager with an useful trade even then the trade is still not very important or very much needed, you could do without it. So basicly most of the trades aren't helpful and if you find a helpful trade which isn't always the case they're by far not as good or strong as any other kit in Lucky Island. My suggestion is to remove the Villager kit or give the Villagers various custom trades.
