I haven't played it in a good while but I have 4 figures in hours of playtime over the years. I'm by no means a master of it and never beat it on any difficulty beyond Nightmare, but have plenty of wins on Normal.

Every time I remember it exists, it steals a few hundred hours of my life until I get burnt out or frustrated. Last big frustration point was that I can't get the random drop which unlocks the extra class in the last xpac I bought.
