Yup. Except WoW devs drew conclusions from the whole Cata launch debacle. I do not know if SE will do the same.

I don't feel like SE made a mistake here, I feel we're witnessing a kneejerk from a few individuals in a community of 26+ million players.
If anything, SE learned from their past mistakes and they're course correcting.

I think Square Enix expected that. As far as I can tell, even Yoshi P mentioned he was getting sleepy in EW content, so this direction is what the team wants and feels is best for the game.
They've been saying for a long time that they want to reintroduce tension in the gameplay. No matter what they do, there will always be people left behind.

Many mistakes were made with the launch of Cata.
