Aradune has been nearly unplayable since launch. I refuse to join a group due to my constant desynching from the server. I tried everything online with no help. Then I decided to check my Comcast modem settings. In April I renewed my contract with Comcast and received the top of the line modem/router and newest TV boxes. (you have to renew or they start to jack up your fees) Long story short I fixed my connection issues by logging into the xfinity xFi web portal and disabling Advanced Security. Comcast is an awful company yet it's the only choice in my area. I hope this will help other people experiencing the same issue.
