Because some "run-of-the-mill" fights are among the most dangerous? And you fight those kind more than once per game? It clearly seems that you don't play ironman.
What fights would that be?
Also 'lol' @ you being snarky all over this thread.
What? I might be if you claim so, in fact i have a tendency to be "snarky" or whatever sometime but why would decide to claim that after my last post? There wasn't anything "snarky" at all in this one. Are you the one being "snarky" here, or perhaps too sensitive?
All the dangerous fights that happen, many times per game. Attacking a big camp, fights during a crisis, especially against a noble/southern army, wurms, possibly hexes with some strong bodyguards, some late(r) game undead armies, hell even a large group of Nachos with the big ones can be very dangerous if you don't pay attention. Fights where you can loose one bro are bad even if you win the battle. And you fight tons of those. The reason I mentioned ironman is because to me ironman is a game of attrition. You can be at your best during a few battles but you can't be (or precisely, I can't) during every battle. You mostly make mistakes during those regular but dangerous battles and bros die. Those battles are the ones that matter most in the long run, even if they aren't hardest per se.
In addition perhaps its a different way to play not just ironman? I never play past ~2nd crisis or so. Perhaps i never become so OP to treat many battles as trivial which comes later.
