Current State of End-Game Contents - A Blog Post from A Japanese Player

I disagree that limited attempt rather than limited successes would be a better time gate- it leads to more frustration and intolerance of people learning.

This exactly. When I was playing The Secret World, this was one of the biggest s***storms among the community - Nightmare Mode raids had a time lockout, win or lose. So everyone insisted that you have to have cleared before to go with them, and it was nearly impossible for those who hadn't already done it to get a group to even attempt it.

At least here I can create practice groups, or even on occasion jump into farm groups after talking to the PF's leader, who'll usually give me an "Okay, but if you screw up twice you're out." Because they're not risking their entire set of attempts for a day/week or hours of effort to do so.
