I'm on Hell act 2 and I don't get the draw for people farming Inferno, or continuing to play on a harder difficulty. If there's no more new game content to be explored, then why become more powerful. Why not just complete nightmare, and go back to normal and dominate. Why farm for increase of stats, when the monsters get more powerful also. Why hit for 5 against a monster with 25 life and enjoy it, but LOVE it when your hitting for 5000 against a monster with 25000 life.
I can understand if people just straight up find the game fun, because your clicking and killing stuff, but once you hit hell and inferno the game isn't stress free anymore.
