Last night in my leveling roulette, I got an AST healer in Stone Vigil (lv42 or something). The party setup was me (DNC), SMN, DRK, AST. By boss two, I had noticed that the AST only ever put cards on the tank. I wanted to say something, but I haven't touched the job since ShB hit, so I don't consider myself knowledgeable enough to criticize.

Side note: I swear I saw at least one Bole and one Spire on the tank, which is just patently wrong, so they probably just sucked at their job, but I digress...


I understand that the changes to the cards means that some cards are better for certain roles versus others, but generally tanks and healers do less damage than a DPS, so my question is this:
Even if the appropriate melee/ranged DPS isn't available, is there ever a reason to play a card on a tank or healer?


Thanks for the answers!
