i agree i like i think the vault of glass was a good example of what a raid should because it requires teamwork, but if someone messes up every one doesnt have to wipe and you can still complete the objective with 4 or 5 people. Now in raids every one has a specific role and if one person messes up or the timing is a little off everyone has to start over. i think the complicated puzzles and task should be saved for the boss fights
