basically you keep doing the same thing over and over and hope that the item you want will drop after 2-3 hours.

why there are so many content in this game that is so painful to play?

always the same thing with boring RNG. Atma, CT/ST/WoD, Triple Triad, Lottery, all different content but designed by the same concept.

Triple Triad is fun but playing with the same NPC for 50+ matches is not fun, and they use the same set of cards in every matches.

people are enjoying it right now, they'll play it for 2-3 days before realize that it's boring.
