Elaaden Vault really really sucks.

Hah, to think that hundreds of years ago, Heleus Ninja Warrior was filmed on the very spot Ryder ran for her life from a neutron purge cloud. 

I know, but some stuff is so good you don't want to miss out on the run... and while I'm already there, I know of this side quest that's related here. Bioware gets that right for the most part, even through Andromeda. However, sometimes, it's just doesn't feel appropriate for the level of the position you hold, whether it being Pathfinder, Inquisitor, Champion of Kirkwall, Hero of Ferelden, Shepard, etc. I also bring different companions to the very same situations to hear their remarks. (Garrus, hands down, can own any scene anywhere, anytime. That's freaking awesome writing.) It gives me another look into their character and nobody else, except maybe CDPR, can even get close to that kind of character building.  

It, and the other vaults, really (and a lot of quests) are bugged, especially if you're a biotic.  Enemies get thrown around or tossed around due to explosions, and get stuck in walls or under the vault or something and can't be reached.  Since they're not all dead, the console interaction never becomes available.

I understand. I've not had that issue with biotic-detonation survivors in vaults (yet), but I've experienced it in other locations. It's silly when you rag-doll and enemy into the stratosphere, or up and over a mountain, and they survive. Some consideration of physics should be involved. I know they don't want biotics to be OP, but come on... If I bounce a dude of a wall and down a mountain, I shouldn't need to track him and make sure he's dead. On Insanity, he rarely is.

I've been lucky to dodge bugs in vaults. I solve about half the remnant Sudoku, and cheat on the other half. It completely depends if I'm in the mood to do the puzzle when I arrive. I'm in my third straight PT, presently, so solving Sudoku isn't high on my list. (I do like the in-setting explanation of building a jardaan phrase/paragraph with these glyphs.) I have a page with all 20 solutions bookmarked on my iPad. It makes cheating quick and easy.

Sort of on a tangential note here, but how is the Voeld vault working for everyone else? My first playthrough it was all cold hazard except for those heating bubbles, but on both my post-1.05 playthroughs the hazard is gone except for the very first chamber after the gravity well. I assumed it was a feature introduced in 1.05, since it was annoying as all hell when you had to thaw out in the bubbles all the time.

I bugged out in that vault once, got no hazard.

Best. Bug. Ever.

I cheat the system in ME1. I use the Lorik Qui'in exploit to max out both Paragon and Renegade, which unlocks both UNC: Besieged Base and UNC: The Negotiation. Of course, ME2 will just assume Paragon if you do this, but I like having both missions so it's all good.

Having to rush back and forth into the safe bubble while you are in the middle of trying to solve a complex puzzle in Voeld's vault is one of the more infuriating and questionable game design decisions I've encountered in a long time.

Yep.  It's so much fun to spend more time in a life support bubble than playing the game...
