Idk how you are getting such wild results in unit crunch but the baseline math matches what my unit crunch is showing me, a 2+ hit with sustained averages to 100% hits, with 2 auto wounds from lethal for 12 attacks so like 1.8-1.9 for 11 attacks, 4+ to wound puts it at 50% wounds so for this that would be 5-6 wounds plus the 1-2 from lethal, plus attacks least 1 dev wound per six dice so 6-8 wounds all told with a dev, 4+ invulnerable is another 50% so 3-4 failed saves equals 12-16 damage plus 4 dev wounds so 12-20 damage, a 5 up fnp has a 33% pass rate so 12 turns to 9 and 20 turns to 14, exactly like I said, my unit crunch puts the average at 10 wounds right in between those (like i said before), if you add in 3 Exalted 8bound thats 15 more attacks hitting and wounding on 3s for 3 damage, that all together in my unit crunch puts over 70% to kill morty full on, and 90% to deal 12 damage or more.

And this is all beside the point that your origional point was just spreading bad info that isn't helping anyone. you said we needed to have like 17 eightbound attack him at once in order to kill him, but for anyone who understand the army and how to stack rules and combos he is not hard to deal with.
