Holy crap that worked! Weird because I swear I tried /ac "Guard" <me> but apparently not! I plan to make a longer macro for multiple guards that pops after my shield lowers so that I only have to worry about pressing it every minute or so as opposed to every 10-20 seconds depending on my shield (currently 13 seconds I believe).
Thanks again REDace0 for the working macro and everyone else for their input
