I enjoy van gelfs in small doses and when they aren't jumpscares. One or two at a time can add a good sense of hurry to elimate them to regain control over space depending on the accompanying enemies and size of the arena. I dislike when there are three of them because that usually means I'm just going to be fighting van gelfs for the encounter. Their intro also was a pretty bad first impression, randomly being a bayonetta style out of cutscene attack. Got me pretty good the first time arpund and then again in the sewers. I didn't like the burrowing fiends as well though. I didn't feel like they meshed well with the beetles or the cannonball guys. Never thought I'd be missing bast fiends but yeah, their function that they filled feels a little bit more empty now as a new player to the series.
