I took resil: wisdom on my barb

[Skrum]

The Barbarian class is particularly well-suited for dealing with a non-sky high Str score by simply relying on Reckless Attack. Str 16 is just fine.

Not wrong, but we play with the flanking variant rules. Gaining advantage is essentially free; reckless is only useful in the random cases where a character isn't flanking (or attacking a prone enemy, faerie fire, etc). It seriously devalues what is one of barb's best abilities, but water under the bridge at this point.

What I would recommend is that you go Bar5/Rog5. The reason is Uncanny Dodge can be used to mitigate getting hit due to Reckless Attack, if you do not a Rage to burn for this combat. Note that Rage damage resistance and Uncanny Dodge do stack together. Eventually pick up Barbarian 6 for that 4th Rage per day.

I'm coming to that realization; 5/5 would be better than 6/4. I might request this change.
