- every death refills your main healing items, so you can't run out
- you keep all the items you collect before you die
- you can recover lost experience points/currency by returning to the place where you died
- you can summon NPC or online co-op partners when you need. This trivializes most bosses.
- other players can leave messages in the game. Lots of them are tricks, but it almost guarantees that you won't miss any important items.
- they're RPGs. If you don't have enough health or whatever, you can level up to correct that.
These games definitely punish you when you make a mistake, and sometimes they are just janky, but if you invest the time it all starts to make sense.
Unfortunately, I think it's their own marketing department that really pushed the difficulty angle, maybe they're trying to back out of that now that they're not an underdog.
