I have been farming the tokkapchi card (the muddy pie) for days. Is that designed to be low like that? And that card can be only obtained by the dungeon, Saint Mocianne's Arboretum (Hard).

I understand part of this game is grinding. But I believe this dungeon is not a msq related dungeon (it was unlocked by a blue mark quest), which causes it to take forever to queue. I wish SE can do something to check if this is a bug issue or at least design a npc to allow players to play card to obtain this card. Comparing queueing for 15mins and spending time doing a boring dungeon again and again, I would rather playing cards with npc to grind this card.

Shouldn't that be the actual design intention for the triple triad card, playing cards instead of grinding it?
