Edit: more detail.
There is a slew of characters that can dependably land any sort of skill test they desire, often via judicious skill use and test manipulation like Lucky! or Live and Learn. For them landing a Brute Force is child's play, even from a startpoint of just 1 or 2 base . Its even easier for the characters starting at 3 or 4.
Static buffs, skill cards or Cornered will greatly help land the bonus damage too. Also give extra consideration to it in latter campaigns, where 3 health foes are more commonplace.
Brute Force can be a brilliant backup or addition to a deck that fights with 2 damage weapons (most 1 hand weapons), if you cant find a weapon the punch can tide you over and you can use it to nail an odd-health foe in less actions then a 2-damage weapon would. It can save a bullet and it costs no resources!
