I'm a bit concerned about enemy movement. Both imps and Hell Knights move around and lunge at you, especially imps. It was like that in Doom 3 already, I think they did that because of the shock factor of a demon getting in your face. I always disliked the dynamic though. Pinkies already serve that purpose. Problem with it is that enemies that approach you like that demand priority. You can't just dodge them and be done with it until the next attack, because they'll be right behind you. You'll have to dodge, focus on the enemy, and kill or reposition (useless with fast imps, you'll have to kill them). If a lot of enemies start to demand your priority it's going to become a nuisance, since you'll have no choice but to focus on these enemies, regardless of what else is going on. So I'm curious to see how that will work out here, with the imps especially.
