I have done to the shards and had to leave, this is way we did it so far, First bit stand on plate till bridge extends then drop, Second bit run to the lights to stop curse stay for a short while till people catch up or till curses completely go, leave people too far behind and watch out for holes in floor you need to have 3-4 good people on plate at end to have a chance and then you run like hell across it. Third part, 3 teams of 2 (i find right side pretty easy so i took it myself but called for help when couldnt cope, you kill sword knight and only person with sword can cross, aim for a knight kill on the other side for each person (only sword can kill a blue knight) on the third person crossing its there turn to open bridge as 4th goes over at this point the ones at start can grt off plate and take out all but sword knight till others are ready with bridge. Next part kill to progress always move forward and then you drop to shard bit if you run and get to second level there is a roxky area which is amazing for this as you have to kill 2 wizards whi h then open door to boss of the area knights etc dont matter That is as far as i got hope you have a vague idea you will see when there :P
