Thank you! Yes, it is very immersive (except for the cars and spaceships as mounts, than can break the immersion a bit but I don't mind it).

Yes, this game can suck hours away, and when you reach the higher levels (75-80) it becomes a task only for the most persistent. It's not a new game, but the update makes leveling a lot smoother and the endgame is only for the most dedicated.
