Very little benefit to having multiple characters which are only kind of good at crafting.
Lucky Charm has seemed to be completely worthless on my playthrough. I have it at around 4 and it doesn't seem to be worthwhile at all.
My Ranger character is the crafter, that's why

I'd keep this in mind for Lucky Charm, even though it has an impact of the offensive rating as well.
But Lucky Charm increases your offence rating by half as much as a point in Dex does so...
+1
Also, having lucky charm makes it easier to convince your co-op partner that you should open all of the chests, and take the best goodies inside for yourself (they'll never know!).
-1

Yes, I don't think blacksmithing 4 will give you anything, and that's the maximum you can get with 1 base.
That's a very good point! I should go BM 2 and CR 1 then.
Scoundrel 1 is just for Walk in Shadows and haste (did you take that at character creation)?
Exactly

You actually dont need to have a fully optimized min-maxed focus super build to play and enjoy the game.
Rather then worrying about it all, instead - just play and have fun with your build, whatever imperfections it might have, because after a while youll realize those are not imperfections at all.
I can understand that's your way of playing but on my side optimizing is part of the fun I have.
Do not put points in weapon specializations until after the mine quests on map two. This is a purposely vague post.
Too late
Also sneak, pickpocket and lucky are all pretty optional to the point they're kind of not worth it.
I'll at least strongly disagree with sneak, especially looking at the great synergy with Guerilla.
For shame! If I'm going to steal from my co-cop partner then I'm going to put points into Barter and convince them to give me all of their salable stuff, and then short-change them after I sell it.
100% agree!
I play only coop and my money is the group's money.
