So an Alliance raid but with a "No Resurrections" quirk.
Not really, especially when BA isn't even a "public dungeon" or "open dungeon", as some people call it. It's an instance inside of an instance and only 56 people were able to get into it at a time, much less succeed in finishing it without being a static. Which brings us back to what you said in your previous post about lowering the grueling process of entry. At that point it really is just another alliance raid but with silly quirks.
The MSQ dungeons are only easy now because of nerfs to the dungeons themselves, high iLvls and massive power creep.
