Druids are probably the most versatile class in World of Warcraft, being able to tank, heal, melee DPS, and supply caster DPS. This makes them an extremely popular class to play in both PvE and PvP.
While able to do anything well, when it comes to PvP and Arena combat, where the druid class really shines is when playing a resto healing build. This is due to the fact that no other class can supply as much healing while maintaining near constant movement as a Druid can. This is critical in arenas as a druid can keep out of line of sight most of the time while still healing their arena partners.
This guide takes you through the basics of being a druid healer in the arenas. It will cover all your key abilities, a basic PvP build, gear to start off with, and the basic tactics you can use regardless of which classes you are teamed with.
