Ok so lets get this straight. Foe requiem doesn't increase any moves for bard (haven't checked with other classes) so don't make assumptions without actually testing it. I submitted a bug report showing through tests that foe requiem is broken a few weeks ago and it has yet to move to another section. Check it out in the game yourself. Try just using windbite and record the initial damage and the DoTs. Then put up requiem and fire at a foe and record again. Requiem has no effect for bard's moves and probably has no effect at all (haven't tried with a mage).
