I do agree with some of the things he said, Like why create such an amazing open world and then instance all the main events. and make all the wild mobs simple trash mobs, I would love to see some more diversity in exploration, where you feel immersed in the world. I by no means have gotten to end game yet and experienced all aspects of the world has to offer but I do see it as something they are holding back on for no apparent reason.

About crafting, I do recall Yoshi-P mentioning they were intentionally keeping crafting simple at the beginning but they have a lot of plans to really expand it in future updates, something to do with balancing the economy, building some core foundations first so it adds more things to build on for later. Possibly just a way to keep players interested.
