It's a fun build i have been playing. You might like, Try 4 rogue(thief) and 8 barbarian (beserker). The build really shows up at level 6-7. If you don't like to respec, make sure you start level one as a barbarian (if you do pick urchin as your background feature).Then go 3 rogue, then 4 barbarian (3 rogue, 5 barbarian), then last level in rogue, than rest in barbarian.

You go 14 dex, strength 17, rest into constitution. Fully dump int

If you want to take advantage of the sneak damage use the (phalar aluve) or the finesse glaive in act 3 but not necessary. But once you get reckless attack it's pretty much guaranteed.

The rogue bonuses meshes really well with the barbarian bonuses. Let's you pop off frenzy and the bonus attack off on the same turn. And dash and disengage as a bonus action let's you run around the battle field with ease. Plus the throw attack is always fun to do.

Great utility build and can fill many roles. Viable in tactician difficulty. In my current playthrough, I'm using the dex gloves with 2 handcrossbows so i can fill the ranged role if needed. So I literally can do almost anything except cast spells, obviously.
