Greetings, Mihana!
Thank you for posting your concerns about the "Guard" animation. As slipmac had pointed out (thanks, slipmac!), we have received previous reports regarding this matter, and it is currently being inspected by the development team. I recommend consulting http://lodestone.finalfantasyxiv.com/ or http://forum.square-enix.com/ffxiv/f...40-Patch-Notes for any details regarding the development team's investigation. Thanks again for your report!
