This is silly. The devs do have perfectly valid reasons for doing what they did even if people don't agree with it. However, as long as it is polite, giving feedback is important and more to the point, as consumers, players are completely entitled to vote with their wallets if it is something they feel strongly enough about.

Unhappy people should be polite and detailed in their feedback but if it is enough for them to no longer want to play FF14 that is their choice and people shouldn't be telling them to do any different. The devs need to provide a product the consumers want and if they cant do that the consumers should look elsewhere until the product becomes appealing again.
