After creating a killer intricate synergy deck for Daisy, where I upgraded for 36xp (factoring in Raven Quill, Refine and Delve Too Deep) imagine my disappointment when my promising bare bones Roland Banks deck ran up against the Xp limitations inherent in Custom Modifications and its associated synergy cards. What a disappointment; what a buzz kill.
Guardians really are the phlegmatic sick men (and women) of Arkham right now. Some serious xp boosting and extra synergies are desperately needed if they're to keep pace with the other classes, particularly Seeker. It wouldn't take much imagination to boldly redefine this class with a new suite of cards that injected more dynamism and excitement into the stogy cast of characters which are supposedly the intended action men (and women) of the game. More than any other class Guardians just don't have any headline shticks that the other classes do (though Mystics arguably suffer somewhat in this regard too), they just don't tick.
