I agree with brasshopper, it's not a horribly usefull song on PC's SO i use it in pulling.
If I am in DS I use it because it has a longer range then my other songs (that i have loaded) and if they are buffed..it' removes buffs and it gets awsome agro.
I would suggest against using this in a pull in a cramped space unless your favorite words are
LOADING PLEASE WAIT (lol)
I have taken on a guildie in the arena and used this when his save magic stats were up to 300 and it went off EVERY time.
So a little fuin in the arena or a wide open space as DS , or me it's not bad..anything else, and you will be nekked in GL donating for rez.
