I think Resolute is a good skill to have a couple of at mid to high levels. Rather than getting dropped relatively far behind enemy lines, it gives the character an opportunity to get back closer to their healers, perhaps even avoid needing a rescue at all.
I think it’s a good skill to have, because if people have it, Plot gets to fight a little more aggressively.
Edit: Also, it’s a cheap way to save a Parry against a big Slay or Eviscerate, like Joe indicated.
