All im saying is from my own experience with hard fights, and fights made hard by limited attempts/time, the whole concept promotes what I feel is bad for the game. It also makes progression more individual skill based, than group based, you will need everyone on the same page, and able to play flawlessly to learn a boss in 5 attempts without small errors costing a few attempts. This is not the sort of group I run with, we have several levels of understanding, but as a group we can learn a fight from scratch and have fun while we do it. This is not even an option now.

On limited attempt boss encounters – Not everyone reads up every detail of every fight before they do it, a lot of what has made this game easy and stale is knowing how everything works, and yet while people know this, they still read ahead. For groups that like to figure things out for themselves, maybe dont have the most natural gamers in the world in their group, but as a group can work together to overcome tough encounters, limited try fights are a slap in the face. We can no longer work on a fight, getting familiar with it, observing all the spells, and helping others through it, without burning all our attempts. We will have to like you said, know the fight inside and out before attempting it if we want a real shot (if its actually any challenge in itself) which just seems like a bad way to make as instance harder, and takes away from the game.
