I played for maybe a year..maybe a little longer. Gameplay is good but there is no endgame and the devs admitted they do not have plans on adding endgame systems. You grind for gear/artifacts and to build up your characters but there is no real reason to even do so. The good news is that you really dont need to spend money. You get a decent amount of currency to roll with just from playing, and the game is not hard even if you dont spend to get 5 stars. All the content is very easy to complete without doing this. So for me while I did enjoy the game there was just no reason to continue pushing. Maybe one day ill come back and catch up in the story, but once im caught up again there is no reason to keep going.
