Greetings again, Janglo!
Thank you for taking the time to create a different thread for your concerns about your character stuttering while going downhill. According to our records, it seems that the development team has received several reports from players that have experienced similar troubles, and the matter is currently being inspected. As mentioned in your other threads, I recommend consulting http://lodestone.finalfantasyxiv.com/ and http://forum.square-enix.com/ffxiv/f...40-Patch-Notes for any news about the development team's investigation. Thanks again for your report!
