Getting really bored.

I think cautious strike is the only dual wield ability barbs have access to, but it also has a CD so gg full set.

That set is very solid, but not best. Its main downside is quite low defense compared to what you can pull of with eth runewords. Id say its the slow that most powerful stat on it.

Ive been wondering - how strong is SSU hundsgugel? I imagine with wolf stance you can have fun swapping points out of rapture into something else, but I don't paladin and I don't know how valuable the skill points are else where. Is there a better item for that slot?

Opens up option to go shadow tree with hand of god. But you are not saving points, since your rapture levle when doing holy tree is low, just to keep duration at reasonable level.
Only skill to save points is leech passive, technically you could play without it, but I don't think its worth it.
Problem with skills like demiurge is, it is good only in areas wher you dont need to teleport. Which is big limitation.
