Help with the build !
Great Thread from Harbinger about Guardian and WWW: https://forum-en.gw2archive.eu/forum/professions/guardian/Guide-World-Vs-World-The-Guardian-and-You/first#post3918826
Though there may be a couple of changes with the new traits (possible use of communal defense in zergs) its still a very sound thread.
Really a lot of builds work great in a zerg due to people balling up. But in a more organized zerg there are better builds.
Some things to remember in zerg fighting: blasting static fields to stack swiftness during the move, blasting fire fields and stacking might before a fight, and blasting water fields during a fight. Be careful with the use of your light fields as they can mess up other fields.
With this in mind hammer and staff are generally very good zerg weapons for a guardian.
