The only flourishes I use on DNC are Reverse and Violent. Kleos -> Reverse -> Evisceration = Darkness. There are probably better dancers out there who can probably help you micromanage steps if need be, but that's my basic go-to.
DynaTav: Body pieces drop from DC mobs (Clusters, Leeches), leg pieces drop from EP mobs (Makara, Bees, Worms). If there's more than a single BST in DynaTav, it's going to be difficult because it just doesn't have the room. For EXP purposes, yeah, you want to kill the highest tier mob possible as fast as possible.
Kindred Seal/Crests go for KS99s and get Behe/Faf/Adamantoise pops.
