Man, this game is so different (in a good way) than what I played on the PC the day it launched in 2012. Great tweaks. Having a blast on PS4.
I don't know if it was just me, if I did something wrong, but in the original PC release, the game got way too hard for me past Normal. I finished the game once with a Barbarian, had really good armor/weapons, and was at a pretty good level. Raising the difficulty and playing through it again, by Act II I was getting absolutely murdered by any special enemies. I would literally die in about 5 seconds no matter what, and the enemies would all regain their health by the time I managed to respawn and walk towards them. It was frustrating as hell, and basically unplayable for me.
Reading through the comments here, it seems like they toned down quite a bit on that, which is good. I'll see when I get there.
