What Are Macros and Why Do I Need Them?
Macros are bodies of instructions that, when pressed, create and execute a certain task. A simple arena macro that is often used is the Arena 1, 2 and 3 targeting system for quick target swapping. Without using a macro, a player would have to manually click the enemy character's nameplate, character body, or use tab in order to target them. By using a macro like /target arena1 and assigning it to a keybind, you can simply press a button and your character will automatically target the enemy player who is labeled as 'arena1'.
Macros encompass a world of different possibilities ranging from cooldown stacking, targeting, kicking, and even dispelling. By going through this guide and gaining an understanding of the practices involved with making macros and how they work, you're sure to crush your own personal goals in the World of Warcraft arena.
Macros will not and can not make a smart decision for you, nor can they break any of the game's basic rules like the GCD (global cooldown). One press of the macro will equate to one button click - you cannot get around this. Click here for the full Macros for Arena PvP Guide
