After spending 5 hours this evening on Grand Challenge with over 20 R+1 and 1 R+2 heroes to choose from, I am done. I have not felt so frustrated and pissed off at a game in a long time - it isn't just "not fun," it makes me angry playing it. I have played this game for at least 1.5 years and sunk in a decent amount of time and money. I believe I will be happier doing something else. Goodbye.
