It's quite a bit insane. After I read of the method to avoid the stupid pre-leveled companions I went from lvl 5 to my lvl 2 save and recruited again. I had no Thievery in the group and that's hard.
I want Sebille as Ranger. There is no good way to make a Ranger in my opinion. I don't want Arrow Recovery but Far Out Man and I also want Thievery 2 (level 1 is not much worth). Can not be combined. In the end I made Sebille a Shadowblade, the Guerilla talent is not my wish but I have to live with it. Such a waste.
Guerilla talent also works with bow and greatly increases your damage for snipe/assassinate on pre emp attack if you plan on using that for massive early damage since that's like the only use for the skill now. My Ifan had to go shadowblade too as my go to second ranger/spear warfare and the biggest waste is actually the 2 on Scoudrel.
