To put it simply : Mana class > TP class

hands down the BLM is first and foremost, any kind of arrow is always welcome
Pure DPS boost no loss
then comme SMN but it force then to rework their mana cycle a bit, huge DPS gain small loss if mana not manage adequatly

then come BRD/MCH and NIN/MNK, the cast class are always happy but can be a bit trouble if short in TP
NIN and MNK have a huge benefit in DPS but inflict huge struggle in TP management

DRG are the least wanted for arrow because their rotation is rightfully calculated... all DRG I know dislike it XD

...

on healer it's good if you're in DPS window

...

Enhanced card is mainly Spear, bole and ewer
because it's very useful on us healer (spear/ewer give a lots of mana if use with LA) Bole always a breeze on tanks
