To start, I really love this dungeon's design, theme, and story/lore. I think Bungie did a fantastic job in designing and writing it and would love to see more content like this be made for D2. I think that it'd be a very fun dungeon to play if the subsequent issues that I'm having with it are addressed. I've been trying to complete Duality solo flawless for about two hours now. There are so many small BS ways that this game cheats you and kills you without actually being difficult content. For example, the absolute two worst offenders in the Duality dungeon are the Crypt slide down and Gahlran's lunging attacks. Gahlran's lunges knock you so far either off of the map or into walls, killing you instantly from physics or off-the-map instant death, and [url=https://youtu.be/y1VoHrF8kRI]the Crypt slide down ruined my latest solo flawless attempt[/url] by careening me down at an insane speed, killing me once I touched a tiny bump at the bottom of it. The fact that this dungeon also relies on brief 1-minute long wipe mechanics, forcing you to rush through every boss encounter and knocking you into walls or off of the map to kill you makes for a miserable solo experience and is painfully unfun for an otherwise innovative, beautifully designed dungeon. You are given zero time to breathe and especially in the 2nd and 3rd encounters, very little if any spare time to kill the Bellkeepers when solo. Playing under constant, unrelenting time pressure for every boss encounter that is only lightly relieved when you kill the correct Standard Bearer is painfully stressful and unfun. I have yet to reach Caiatl's boss fight solo, but from my experience doing it with a full team, I imagine that it will be equally as miserable as Gahlran's boss fight due to the endless waves upon waves of Psion snipers and Centurions. If your build isn't absolutely perfect or stupidly OP to survive this enemy spam Hell, you will likely be unable to solo flawless it, let alone solo it without spending many hours of your life trying. I am aware that [url=https://www.youtube.com/watch?v=U_bWW0iMXWo]Saltagreppo recently solo flawlessed Duality[/url], but he is an insanely talented player and probably within the top 0.1% of PvE players for skill given that he solo'd Atheon too. I would hope that players of his caliber weren't the benchmark in designing this dungeon's add density/spawn frequency and mechanics. Before anyone asks: Yes, I know dungeons are far easier with two other teammates to help me. In fact, I completed it with a random LFG team today upon finally mastering its mechanics. Yes, I know I do not have to solo/solo flawless this dungeon. However, if I want to get the Duality seal and title (which I do), I must at least solo it. I've solo flawlessed every other dungeon in Destiny 2 and none of them were as miserable of an experience as Duality has been so far. I and other completionist players who enjoy challenging ourselves are likely equally frustrated by how you can easily have your attempt ruined by stupid deaths like dying on the Crypt slide. I really hope Bungie's dungeon team reads this and listens to my suggestions, because I think this would be the most fun dungeon should it be made slightly less punishing in terms of the time-crunch and enemy spawn density. At the very least, it would be fantastic if slightly less enemies spawned when running solo, but I don't know if that's something possible to code this dungeon for. Less ways to die from getting knocked off of the map by bosses or randomly die from the map's physics would also be great too.
