So I'm just about finished meriting BRD and this is how I've done my merits.
8/8 Singing
8/8 Wind
(When I level WHM I'll be removing 8 out of wind and putting it into healing, I might even move 8 singing out as skill is less necessary these days)
5/5 Nightingale
5/5 Troubadour
(Having 5/5 Night and Troub is handy as hell with Tenuto + Ballad combos. Adventurer's Dirge and Foe Sirvente were incredibly limited @ 75 and even more now)
5/5 Lullaby Recast
5/5 Finale Recast
(Lullaby is less useful now that we essentially have 3 really potent sleeps, but it might come in useful. Finale is useful and fast, I haven't used Madrigal, Minuet or Minne for a long *** time, they are pointless and when you do use them the small increase you achieve from meriting them isn't important at all. Please let us merit March SE, even though that wouldn't be that great anymore)
So is that about right? I'm pretty sure it's good enough.
