I just got this last night and since we only use DKP in 25 man or over instances , it didn't cost me anything. I agree it's not something you'd want to wear all the time, but maybe after long fights while you're not doing much for a while--lol.  I only use AoTV when my mana bar gets down to about 1/3 and it looks like I might run out, never at the start of a fight. No way this belt should be an epic and you're right, the Gale force belt is better.
