So I had suspicions of this a few times while lvling up corsair in the low levels but ended up dismissing it and not thinking about it much until reading this post. This is absolutely happening to my corsair. My rolls aren't effecting me or anyone else. This is not across the board all corsair's for sure as I play in endgame and corsair is a game changer typically. It seems to be some of us new corsairs. Mykuroichi is just a couple months old now. I do hope this will be addressed because I am loving the job but am sort of on hold wondering if it is going to be of any use to me.
Here is my /checkparam before and after hunter roll displaying the same accuracy. Accuracy then rises after eating akamochi +1 so /checkparam is infact working.

Here is my first decent challenge mob 86 experience points no corsair's roll.

Here is the next mob with corsair's roll on same experience points.


A 3rd fly same corsair roll still active

Then checked to see if my rolls are doing anything for party members. Accuracy has no change after roll.
