Draugr Warriors are essentially just Draugr, except they can imbue their weapon with fire. Getting hit multiple times will set Kratos alight, dealing damage over time. Outside of that, the same tactics apply.
Draugrs are armed with a crude one-handed weapon, their attacks aren't exactly slow, but they're easy to see coming.
As long as you don't allow yourself to be surrounded, standard Draugr shouldn't pose much of a threat. You can either smash them into the air with a heavy attack and follow with a combo, or put your weapon away and fight them barehanded for a very quick stun finisher.
