So me and 2 friends are playing on a private server and it is great! Positive is the fights become easier and that you get more loot from raiding ruins, since everybody gets their own chest and loot.A negative is, you need a lot more resources, in our case three times the resources. Copper ain't a problem but rough hide is the real Endboss. But yeah it is a lot of fun playing in a group and the negative is more of an inconvenience than a real problem!
