Personally, I don't agree that it should scale to fireteam size, and this is coming from the experience of solo flawlessing each Dungeon that has been released so far. What it needs to make it better, is to scale the [i][b]damage phase window[/b][/i] to fireteam size. Give the longer window to the solo player and the shorter one to the three man fireteam. I haven't finished my solo run but by my estimations it is going to take me 9 damage phases for the first boss, which is of course 18 cycles of the mechanic. This is borderline insanity to expect players to slog through for not even being the final encounter. The amount of time given for the damage phase is barely enough for me to empty my Grenade Launcher and use up a Geomag boosted Chaos Reach before the boss goes immune, which is far too short. I'll get it done but I'm not thrilled about it. So far the Dungeon is giving me flashbacks of Ghosts of the Deep, and I really hated running that Dungeon. Between the instantly respawning adds being impressively annoying to the even greater over-inflated boss health pools, this does not feel enjoyable. I would place this between Ghosts of the Deep (being the worst) and Duality(at 3rd place), for the worst Dungeons released so far, and that is saying something considering how much I enjoy the Bray lore, though I will need to run it a few times before I really get to know it. I will say I do appreciate the Class Item being behind a puzzle instead of being part of the loot pool, plus the ability to focus a reward, which is a nice improvement.
