I lag constantly whenever there's a handful of players around me. By lag I mean actions don't register, the picture stops, my macros skip a step and lag - like a latency of some 3 seconds between my input and the output. I don't think it is because of my internet connection, but because I'm on a old PS3. Then again, sometimes I don't. I never had this problem during the Betas, and I only noticed it right after they fixed all of the errors in September.
