It's the same for me. I wrote macros for making crafting easier and they simply don't work because of the server lag. I go out gathering and sometimes it takes damn long between gathering attempts because of server lags. I farm some monsters and everything freezes for 5 seconds because of the server lag. I did the ifrit fight and got hit from every AoE because of the server lag. Than I did a ping test to my FFXIV server and saw that I have latancy values between 300ms and 400ms constantly and even lost packages while pinging the server. That's definatly broken and it should be their top priority to fix this.
