Except a big difference is that this game is an extremely linear yellow WoW exclamation mark quest based game in 2012 that leads players to believe that 'if I've made it this far, I should be able to keep going.' There's not even a WoW style quest color system that says, "Oh shit, this area is RED or ORANGE, I might need to figure something else out before I go further."
You can't blame players for that--Blizzard designed a linear game with hardly any randomization that doesn't at all indicate that you ought to be required to spend more time in an area before you move on.
The whole game is a point to point escort quest funneled along a very narrow corridor. It's not a player's fault that they think they should be able to progress since the game very actively placed them in that position and directed them to move forward.
You can't absolve them of sins they are making today and say that "D2 was like that"--and then when someone wants a different aspect to be more D2 like, turn around and say, "Well, this isn't D2 anymore, sorry."
Pretty sure dying over and over is a good indication that you need something better to move on. Unless you're playing hardcore, death isn't even that big an issue in games like these.
Do you expect Blizzard to put up signs detailing what the minimum item level requirements are for harder difficulties? Or that maybe as a Barb they shouldn't be stacking intelligence as much as they are?
