A skill to make a save each turn for statuses, or automatically making saving throws against certain statuses each turn could be interesting. Automatic saves for fear, restrained statuses, knockdown, stun, etc. make the most sense. Maybe some other statuses, like poison.
The problem with saving throw for statuses can be solved by having them for less turn if your stat is high enough.
I have the impression that D&D try to put saving throw during your turn just to avoid boredom ( D&D fight tend to be long ). In this game all the fights will be faster compared to a Tabletop so if your character have a good Constitution/Vitality he'll be poisoned for less turn. I think it's not going to be a big loss.
Death saving throws or another to rework death from this meaningless thing cured by a cheap scroll, is definitely a priority for me.
Imo death is one of the main reason why D&D ( and any other tabletop rpg ) is cool. Your character can die, so you need to reroll a new one. So yes this is super important. I think it will be easy enough to remove totally the cheap resurrection scroll and increase the level needed to get a resurrection spell. Am I wrong?
I agree the excessive environmental effects aren't super DNDish, but not sure how one would dramatically reduce their presence. Perhaps if electrified water/blood un-electrified after 1 turn, poison and oil depleted after a bit, etc. that'd be a big help.
As Noctro also wrote, there should be a way to control the timing for those effects. But I don't think they aren't DNDish. I mean... well... fire+water=nomore water
