I haven't found a need to cast madrigal since I got minuet 4. Double march for most situations, or double minuet for zergs/rangers. This was long before abyssea too. Zergs inside abyssea may not require double att either, as some jobs will hit 999 att with gear/JA/food/atma.

I'm 5/5 Minuet, never decided on finale or lullaby, so didn't merit it yet.
1/5 both troub and nightingale. Haven't really found a need to drop the recast timer, but I haven't had to go brd/blm to the likes of cerberus or HNMs that have high resistance vs elegy. For these cases, having T and N in line with ES makes lots of sense.
