Mine was actually pretty good around launch. Now almost every fight is a lagfest. I'm wondering if everyone with a decent net just left due to lack of lobbies.

The netcodes been good to me. Pretty sure I even played Americans that showed as 3 or 4 bar and it ran well. I avoid WiFi. I always thought DoA had its little lag issue's due to so much that actually happens in DoA fights. Between the freedom of character movement and the stages.
