There is a core difference between everything else and EX.

When you did any of the other dungeons, raids, trials,alliances or Guildhests for the first time, you went blindly, you figured stuff on your own or asked/received advise from someone who had already done that dungeon/raid/trial/alliance to explain the 1-2 mechanics to look out for. In short, you went in unprepared.

When you did an EX fight for the first time, you did so either with a group of people that were also first timers during week one and made prog together, or you did so with a group of people that watched a video or read a guide after they came out and made prog together. In short, you went in prepared.

So how is it fair that just because it's no longer the current endgame people can queue unprepared for content that is NOT novice AND expect someone else to carry them?
