We should let the developers do their thing, but at the same time we need to give them feedback aswell. The developers are not making this game just, because they like to make games. They are part of a business and this business needs cash flow, otherwise FFXIV would have been a free game. Since FFXIV needs cash, it needs customer and we the customer have stuff that want or expect from the game. If the developers ignore the players, then they will not know what we, the players like and dislike. SE has people that will filter the good suggestions from the ones where people are trolling.

Feedback is important, we should give it (I wish developers brought back the ingame polls from the BETA) and developers need it or else the game will never improve.
