Guardstance?

No actually I had to go to work, but once again this is all speculation, with comments like "seems" in there does not make the statement anywhere near conclusive. The only people that can confirm or deny this is the development team. There is math that does determine the boundaries of actual damage reduced, but ultimately that is just a set threshold, everything else goes off of the tic function which is predominant in almost any programming language that generates a "random" but not really random number within that threshold, therefore it is entirely possible that guard skill at higher levels can reduce more damage taken as that threshold can change with the values of the skill.

Guard has been discussed and tested to death over the years. If there were any damage reduction benefit with increased guard skill, it would've been found ages ago, but it hasn't been found, because that effect does not exist.

And honestly, unless the devs make some some radical changes to the way guard works, it's not worth discussing any further, for reasons CS and others have elaborated on in this thread and elsewhere, dozens of times.

I love how you back pedal.

"oh go do the research, I'm right you're wrong"

Research is presented

"oh, only the development team knows"

Not the same tune you were singing earlier.

Here I'll clarify it for you. After extensive testing, it has been found that Guard has an effect of ~1-PDif. Additionally, Guard has a very low proc rate, such that if the mob is difficult, then the difference between capped and uncapped Guard skill is nonexistent(read always 5%).
To put it another way. Guard is to MNK as Staff skill is to SMN. It doesn't matter how pimp your gear is, Melee SMN is going to be bad.
