This is a collection of 5 auras:
Windburst (icon)
Lock and Load (icon)
Marked Shot (icon)
Marking TGT (icon)
Vulnerable tracker (aurabar)
This is a simple set of Weak Auras that I use on my MM Hunter that serves only as a set of cues or prompts for what is happening in my rotation. It makes use of the Vulnerable Tracker created by Azorthorian and adds some audible cues to what is already taking place in the base UI with respect to procs. I find that having both an audio and a visual cue helps the player stay focused on the important bits of information they must attend to.
