I've been hoping to see the Cacodemon and lava/acid get a bit of a nerf. At present, the Cacodemon does more damage than a Hell Knight and has a bigger splash. Canonically, I feel like the Cacodemon's attack has always been easy to dodge, but in DoomRL they consistently pound you with merciless accuracy. While 40 health is about right for DoomRL-Doom scaling, shotgun rounds seem to slide right off them and going toe-to-toe with chaingun or chainsaw is asking for a Pyhrric victory. I think the game would be more true to source material (and a little more fun!) if that big stupid red tomato had less splash and less accuracy.
Also, I can't really understand why floor damage was increased in the last patch - Doom floors did about 5 damage per week. The buffed floor damage is irritating because it has made pulling levers exceedingly dangerous, you can lose a bucket of health trying to pick up an item that was hiding lava, and getting to the secret rooms in Chained Court is not worth it anymore.
Would love to hear your thoughts on this, Kornel!
