I'm on PC and use a controller, I've also noticed my controls are "slightly" messed up, but only with a single job. My BLM will always autosheath his weapon and never counts as being drawn. This conflicts with the way my targeting is setup which causes oddities.
I've also noticed this only takes effect while in duty, if I'm in the main world I'm fine, as soon as I que, controls are messed up.

I have no issues with this with any other job/class, and it only started happening today. So yeah, I'm with you here.
