@beardalaxy For me was the arena shooter aspect, i can't stand arena shooters. Sometimes it's fine to enter a area and all the doors close down and hundreds of enemies spawn, once or twice a level, but Doom Eternal was almost just that.

Also i hated the "No Child, you will not use this weapon against this enemy! It is incorrect. We laid down a correct strategy of engagement, and you will have to follow it, otherwise it is unoptimal, enjoy suffering". They couldn't create ways to engage the enemy in different ways, if a cacodemon shows up you HAVE to make it swallow a bomb and do a glory kill, if a arachnotron shows up then you HAVE to destroy the tail, if you don't then you will lose a lot of ammo or health, 0 alternative ways to engage.
