12/36 for me, 19/40 for her before the +25 for the Shock potions. It isn't the resistance/armor.
I think the fact you're a good 5-6 levels over the content (I want to say Trollfens is about intended as a lvl 13 zone?) is clouding just how effective you think Companions are.
Once again, as I've stated elsewhere, the difficulty is pretty good. It's interesting again, and with more content to avoid simple dungeon runs to level and alternatives, it will be great. But more than anything, I'd like to see Companions worthwhile beyond quest unlockers or secret finders and be able to try new ones without being hosed because their level is a lot less.
I know, the half XP is coming, but being 2 levels less with their reduced stats/skills along with the jump in mob strength over 10 I don't think it will be enough to make them... I'm trying to think of the right word here. They're not supposed to steal the limelight, and they are useful to a degree, and I do like the difficulty but... eh. Inadequate?
