Macros

For the longest time, I played with no macros. The first ones were things like /p /cast ones to tell people I was feigning or bandaging; it wasn't until we were hitting the later parts of Karazhan that I made something more useful - the first /castsequence I used. That macro was made because I knew I wasn't using Steady Shot enough, and it would reinforce me using it, along with (at the time) Aimed, Multi, and Arcane.

This is a consolidated list of my current hunter macros. You may notice that I'm fond of left click/right click/middle click macros for some things.
