If you had the patience to create the 24 macro for your card
Then I admire you XD

Spear do reduced CD that have been activited... But it only work on the overall cooldown...
So if the CD is already 25% refresh the spear is useless.
Which is... 98% of the time (well maybe it make you gain 2/3 second on draw or essentiel dignity... But merely useless..)

Ultimately
The best card is balance it benefit everyone except full healer (would be fun to have balance enhanced pour heal from 10%)
Arrow work best for Blm and smn. Mnk, nin, brd, drg will like it but it will burn their TP. Tank and heal will be... "Meeeh"
Bole work for tank enhanced or long it always good
Ewer on heal or bard, smn won't mind too, Blm will dislike it
The spire, every physical will appreciate that, mnk, nin and drg first. Brd and mch if they aoe, tank if they go wild. Useless on EVERY caster XD
