I am re-addressing the game freeze (Random Non-Responsiveness of this game) and Rubber Banding. Dating back to as early as Feb 2015 folks have been reporting this issue yet I have not seen a fix in patch notes or response from ZOS.
Now add audio and crashing issues. All week folks were reporting audio issues and 64bit client crash issues and none of those were addressed in this Monday's patch with the exception of the MAC client crash issue. ZOS, the ESO game performance has been on a steady decline with every new update or dlc. I do not want to guess your plans but you need to get a handle on these issues and fast.
