Darmanitan is hit neutrally by all-but-two priority attack, and neither form has enough defenses to withstand them.
This still needs fixing. Darmanitan is weak only to Aqua Jet, is hit neutrally by Sucker Punch, Extreme Speed, and Mach Punch/Vacuum Wave, and resists Bullet Punch and Ice Shard.
In Daruma Mode is also now Zen Mode. It additionally resists the fighting priority attacks, theoretically giving it more opportunities to switch in should one decide to run such a set. Its worth noting also that Zen mode's defensive stats almost double from its previous form.
You've been saying "logs or it didn't happen" in regards to people claiming such a set could be viable, likewise I challenge you to provide some calcs with respect to both forms' ability to take certain common attacks, especially priority, so that we can accurately see the difference in defensive prowess between the two forms. Given that it only gets said defensive stats at half of its total HP I think a lot of people are curious about its ability to take hits in such a scenario. In fact your analysis is looking rather scant in general. It looks rushed. You should go a bit more in depth about the individual sets IMO.
