Darkmoon Card Problem

Alright so something I want to understand. I’ve been observing naturally the number of players is decreasing week by week as people get all the gear and rep grind. How are we going to get any cards in the economy of literary no one is doing dungeons because everyone has all the offering gear… and it’s not even possible for a single person to farm them because in 50 dungeon runs I’ve only seen 2-3 darkmoon cards.

What’s the plan here how can this be sustained the cards are already unoptainable now at 4k+ gold prices. I think cards should be able to drop from all mobs in world otherwise the supply will just dry out and soon.
