I will say, that while the "One person fails, therefore wipe" makes sense in theory, in actual usage it was a pretty bad idea. The party I was in never failed the mechanic (We did wipe right after it, though. No tank LB used. XD), but I can see it having been an issue.

In terms of "Do this or die" mechanics, it's not a terrible one in most cases. This one is just extra long and extra punishing for those who aren't the best at it (or hit enter).
