you can also set up the ability to a hot key with the usuall AA method which is my perfered method of using this.
it is important to note this can be used for things such as group healing an entire raid with a cleric (which will mean certin death for the cleric) however I have found that if you click MGB then use celestrail regain (cleric heal over time AA with no agro associated as far as I can tell) entire raid will get the HoT without you getting any agro.
I suspect this will work with other AA too so if you are about to burn an AA such us the druids gift of oak or whatever there hp/mana regain is or bst PoS you might try MGB and presumably you can hit everyone around you with it. If your not using MGB to keep your raid buffed and that MGB is sitting unused why not click it before clicking your AA's and let others weep the benifit? The people in your raid getting free mana hp or buffs they never expected won't complain
