It's funny because I loathe that mechanic. As a healer main, I'm... irrelevant. The game forbids me from doing my job. Not only can I not prevent it (which is the point), I also can't recover it. Whoever failed it gets to watch the game for a few minutes and do nothing (or more likely: get up and get a drink) and I get to not do what I'm there to do. It's not fun for anyone.
The revised version on something like Ravana/Bismarck (or Hashmal's tower crushing) are IMO far better. They clearly punish anyone who fails tremendously, but not in a "you're watching the rest of the fight and I'm powerless to do anything about it" way.
