Right now, in my head the analogy is: stuff that you do from torment 1 to 16 are equal to normal difficulty in D2, GRs from 75 to 110 equals nightmare , and 110 to 150 equals hell. In terms of how much content this is, 90% of the game, (the acts, the bosses, the world, the areas, and pretty much everything there is programmed into the game) becomes obsolete the moment you do a seasonal journey and grab your set.
My oppinion is that diablo 3 has been programmed to be more casual friendly. I am not saying it’s a good or a bad thing. Someone else might prefer it this way. Personally i dislike it. D2 was challenging for most new players even in the first act on normal difficulty. Dying was also punishing even in softcore where you had to go and pick your body again in the thickest of things to recover your items. Yet, now if you die, you just wasted 2 seconds of your time and 0.001% of your total gold to repair your items.
On the other hand, now we also have tones of legendary drops. You finished an activity that took you 3 minutes? Congrats… Here are 12 legendaries for you. Yes, i know there are many ways these items roll and you want the good rolls. But remember how unique and rewarding was in D2 to find a piece of a set or a unique item…
That’s why i would love to see a remake version of D2, without some of the annoying and outdated mechanics like stamina, gold that you have to pick up manually and ridiculously limited stash space.
