Important aspects to the story that were just dropped

[Lauront]

Boom. Nice idea right there. yeeahh it took a while but I eventually realized that the ongoing story never measures up to the stuff we imagine. Charitably it can probably be blamed on time and budget constraints. I do have respect for the writers and all the staff. Their hands are probably tied in many instances, like the fights are already decided and they just gotta write around them. The lore / backstory sounded so amazing from the start; the stuff we get to witness first-hand and participate in can never measure up. The CGI intro movie to V1 with a bit of battle of silvertear lake is still one of my favorite things.

From what they've said, they had material for another 1-2 expansions, that ended up being compressed in EW, e.g. see here or here. I get a definite sense that Yoshi was in a rush to end the current arc.

Well that is rather silly. Hopefully they get addressed ever as they were shown in ARR.

EDIT: Actually this reminds me please stop putting all these answer in interviews. We have an in game compendium, use it.

Agreed, I find this annoying, as well. If an attempt was made to keep the codex relatively unbiased (or rather: make it clearer that it's written from a certain someone's perspective), it'd be a good destination for this kind of source material.
