The one thing that I feel like holds this game back a little is the heavy handed tutorializing. I get why they did it, but I feel like it sells the game short.
It's the exact same issue Sekiro has, actually. In that the game gives you a very efficient way of dealing with each move through unmissable pop up tutorials. And since every player knows how to deal with everything, they never experiment, and go on to claim that the game has no room for doing anything differently from the exact approach the game wants. And it doesn't help that it's pretty close to optimal.
But in Sekiro, the way this hurts players is that they never try new approaches, keep doing the same thing and dying over and over, unable to beat the boss. This is a lesser issue, because if they're failing, then the game is already communicating that there might be a better way, it's their fault they're not listening.
But in Doom Eternal, what happens is that they give you the answer that would be cool to figure out by yourself. For example, the shielded dudes appear, and the game instantly tells you to switch to the Plasma Rifle and shoot their shields so they can overload and cause an AOE blast. Why would you ever try anything else? If it said nothing, more people would likely realize that they have openings in their shields for their hands, and shooting their hands with the scope will disable the shields, Halo style. Then, later, either they'd try it out by themselves or they'd read someone mentioning online that you can actually blow up their shields with the Plasma Rifle.
That still trivializes any other approach, and will be the one they'll use every time from now on, but it feels like a discovery, like experimenting with the systems lead the community to the correct answer, instead of just being handed that answer on a silver platter. I'm sure other ways will be found with time and the meta will evolve to ignoring most of the tips the game gives you and favoring something else instead, but for a first playthrough, you're basically just doing what the game tells you.
This is a minor issue for me, I should say, since Sekiro has the same problem and it's one of my favorite games of all time, and Doom Eternal so far has been easily one of the best FPS campaigns I've ever played, but it's something to keep in mind for a possible third game. I know the director said that the game is not about figuring these things out, it's about execution, but a lot of people have been criticizing the game for lacking that experimentation period.
That being said, a negative consequence of getting rid of some of the tutorialization is that the game will have to become easier on all difficulties. They give you the answer to every enemy, and encounters are still pretty fucking hard, so if you have to figure out a way to deal with them yourself on top of that... they'll likely have to make it a little more manageable.
