The release of HW was split between two things: leveling content and endgame content. On this matter, I feel like they got the balance of endgame content just slightly off; Gubal and Aetherochemical should be available as Expert dungeons in my opinion. That would have done TONS to alleviate the mountain of "only 2 dungeons!!" complaints. Now that HW is actually out, they can focus on additional endgame contents instead of the leveling experience, meaning each patch from now on is going to have more to do at endgame.

Second, they've made it very clear that a 5-month patch cycle is not the norm. After 3.1 it's going to be back to 3-4 month patch cycle. I do think it would be nice if they let everyone know they were taking a month-long break after HW beforehand so there wasn't this "surprise! we took a break!" business
