A simple Weak Aura I created for Classic World of Warcraft to remind me to cast Battle Shout. A mini Battle Shout icon will appear under your mouse cursor whenever you are in combat as a warrior and do not have the Battle Shout buff active. It will work in all stances (you can change this easily enough in settings if you only want it for a certain spec or stance).
I did not see a Weak Aura listed for Classic WoW that has the Battle Shout reminder on the mouse-cursor so I just created my own during the Beta. I find that having a small reminder on the cursor gets me to cast it the quickest and I also prefer it aesthetically.
I have used this from level 1 on my warrior and it has VASTLY increased my Battle Shout uptime, likely near 100%. I choose to keep this on when I am tanking too, considering Battle Shout is very good at generating threat.
This is my first ever Weak Aura, please let me know if there is something I could change.
