3v1 when the One apparently is Elder Ironbrother tier is worth slamming the Panic Button. The guy almost one-shot us rememer.
Bluntly, I don't think this is true, although I think you may have posted this before IF confirmed that we could definitely have won. Like, I don't want this to become "Skippy harangues the thread again for being insufficiently bold and not playing in the mindset of a Norse warrior", but since you ask...
..fighting three on one isn't a reason to start looking for panic buttons, it's a challenge. The kind of thing that a great warrior is excited by, feels their blood pumping hot in their veins, and rises to meet. That's the mindset of a hero like Blackhand, and that's the standard we're being judged by here. Also for what it's worth, we wouldn't have had to fight three on one because Axe Man was clearly winding up to strike first, giving us an opening to do a Contested Movement, and Spear Guy was backing away because we'd broken his spear. This was spelled out to us to us in the tactics section of the last update.
But I think the main thing here is more, uh... how we react to situations like this, I guess? If you look at situations like this and start from the assumption that we're doomed. doomed, DOOMED, then you're always going to be able to find evidence which confirms that. If you look at situations like this instead from something more like a growth mindset, seeing it as a challenge we can overcome, then you aren't tying your own shoelaces together at the start of a run before going "look, there's just no way we can do it".
