I don't know what your source is, but most of them are outdated. Exhibit A: Arans no longer have Freeze Standing.
For the first: Doesn't matter, Xenon has different skills from the rest of the resistance, it's 90%.[/quote]
I agree that Xenon skills are different, but Xenon is still technically a resistance class, so saying all resistance classes have 100% stance is incorrect. Which, admittedly, I don't really care about, but still.
Unless Dual Blades on longer have 90% dodge, their effective stance should be 99%
Cannoneers should effectively have 87% stance, given that they have an additional 35% counter rate
Hayatos also do not have any stance while using the Sanrenzan skills, although it would appear to be so if you can kill mobs fast enough/keep the mobs far away enough with the KB. However, Hayatos do have evasion and avoid rate; I cannot find anything in its skill set pertaining to dodge.
