Regardless of your opinion on BLU, expecting an immediate response is ignorant to the point of laughable. The devs have been extremely transparent about the time it takes to develop content, just look at their interview about Eureka, where they talk honestly about their intentions and what they learned from the content. One thing of note from it is that they say that feedback from Anemos couldn't be implemented until Pyros (which did make significant improvements) due to the Pagos already being in late development by the time the feedback was in place. They can't just drop everything because you didn't like it.
So when people say "why aren't they talking about BLU?" or worse "They need to fix BLU before 5.0", it sounds more entitled than it should, because it throws all logic out of the window in favor of "I need it now". Despite the narrative that is spun, the devs are very good at taking on board feedback, they are just a bit slow about it (as is expected in an MMO where there is no time to spend on feedback and something is always being worked on, *cough* expansion *cough*). People will call me overly optimistic, but why do you think they released BLU in 4.5 instead of 5.0? They said in 3.5 that Zhloe custom deliveries were implemented to test the content during a content lull, and I firmly believe that BLU is in the same place, an experiment to improve in time for the new expansion cycle.
