Unlike the last Doom, Eternal is much more about resource management. Try to get into the habit of consistently using your secondaries because the difficulty curve expects that you're constantly switching between chainsawing enemies for ammo, pulling glory kills for health, and setting enemies on fire for armor. Using "the right gun for the right enemy" is de-emphasized compared to the last one in exchange for being able to use the best weapons more often if you're smart with your secondary abilities.
