Depending on your server and who you are linked with chances are you may be playing on the down time and not prime time. One thing that may help you is to find a wvw guild weather it is a zerge busting guild or a small roaming guild. By joining one of these they can help you learn more about wvw and you will also have a group to run with. Most wvw guilds will have rally days and times set up for everyone to play together. If you don't want to join a wvw guild that is ok just ask in team chat if anyone is currently running a group and can you join them. Chances are people are running tagless I hope this helps make you have a better wvw experience.
