Lone Wolf is broken trait, therefore no NPCs at all are allowed I think.
Playing Lone Wolf and then getting companion from your friend would also kind of defy the purpose from your trait.
Nope, works just fine on companions, as long as it's just two guys in the group you get the lonewolf bonus. Which makes it basically a talent which you should take twice or not at all … at least from an efficiency perspective. Running currently my single player run with two lonewolfs, Sibbil and Ifan, great pairing and great theme with them both running lonewolf.
Lonewolf is supposed to make a single character as strong as two ... not as strong as three. So theoretical having two avatars, one with lone wolf and the other with an companion instead should fit the purpose. Now from a balancing standpoint you might be right. Lonewolf might be indeed a little bit on the strong side and instead makes you worth 3 characters, but in that case having a party of two lonewolfs defeats the purpose even more, because you get a party of two, worth 6 characters. Instead of limiting the party to two. The talent's implementations seems overall not polished at all. The implementation of Lonewolf takes efficient choices away from the player, not only because it is rather strong, but as well because it can cause a conflict of interest in multiplayer when one player wants to take it and the other does not. Meanwhile in DOS1 the talent was on the strong side as well, but at least worked fine in a coop run without causing any trouble.
TLDR: You stand corrected. ;-)
@geala I loved the surface game in DOS1, it just seems that the UI and controls are actually worse in DOS2 to play with them. Well, that and the good old barrel game is not nearly as fun as it used to be. Heavily reduced in damage.
@Yasen Never mind, I was just ranting to get my frustration out of my system. Worked btw fine, even when I can write one rant after each play session. Larian seemed to have run out of money or time, the game is definitely not as polished as the first one, but it seems a lot bigger, which might explain the lack of attention to detail. A shame, because that attention to detail was what I felt in love with during playing Divinity: Original Sin.
