It would be nice if this game had a card game as a mini game like they did in the old final fantasy games. It would bring a new layer of fun, and competition in this game.
They should have some player vs player tavern games, but not anything like Legends. Dice, simple card games, etc. On the order of Caravan, and without P2W Crown Store cards.
Although, for people who play both Legends and ESO, it would be interesting to be able to play with other ESO players using Legends decks. Not that I want them wasting ESO development budgets on it.
