I'm not trying to be elitist when I say this, but I've never experienced a wipe in PotD and the content makes me very sleepy when I do it. It's not the relative lack of challenge because expert roulette doesn't do that to me. I think it's more the bland, boring copy/paste rooms and seeing them over and over and over.

That said, even though I've never experienced a wipe, I don't like the traps. The main issue I have with them is that outside of having a pomander and not being oblivious to them (sadly, lots of players still step on them even when visible...), there's no action that can be taken by players to prevent tripping them as they're quite literally invisible. There's some player skill involved in surviving the worst of them (I intentionally avoided tagging multiple mobs when a DRG face pulled an entire room and then hit a lure trap so that when the rest of the party wiped I could finish my mob, avoid the mobs leashing, and revive the healer after the patrol went by), but I abhor the fact that tripping them is random.

I would have very much preferred a system like you see in Skyrim where the traps are visible but blend into the environment well. Even so, there were many traps in Skyrim that you'd just hit anyway because you just didn't notice how well hidden they were. I feel like more diverse environments rather than empty box rooms could have lent well to this. Pressure plates, trip wires, bear traps like we see in Hullbreaker, a rune that activates if you cast magic near it, etc.

I just wish the tripping of the traps were a more interactive experience than it currently is: stepping on them because they're literally invisible.
