So by NOT implementing the 5e rules right, in order to make people happy and give them more super-hero like characters from the very start, they are dooming the later levels which will then make it harder in the long run. I'm afraid they are going to have to really tank Level 10s so much that they will be even further from 5e rules in the long run, doing things that are so ridiculous that it will be beyond superhero status.
The main reason I am not worried about that personally (about them gimping the later levels), not sure if you played DOS:2, but there was a huge jump in difficulty when you left the starter area. Everything just really started hitting harder. I mean of course as you played, got better gear etc it leveled out, but when you first head over, it is noticeable how much harder it got. So I am assuming they will do the same with this game.
But then again, we are in a time of game development where they seem content on making games as "accessible" as possible, not wanting to be accused of elitism or gatekeeping by the game journalists (literally, some bile comes up when I call them that today lol), that it seems they are making games way easier. Which I hope is not the case in this instance as well. Keep in mind that there is still people that come on this forum, or the reviews and complain about how difficult the game is, which honestly I cannot understand, but there it is.
