Romanito, I completely get you. I feel the same way. I recently got access and also feel extremely let down by this feature. It is such a cop out.
I understand that this is how it's going to be, fortunately I still think the gameplay is excellent once you get used to this annoyance. Give it a chance. Suffice it to say, I will be crushed if popular opinion causes Star Citizen to go the same direction with this.
Some things addressing arguments in favor of the bad yaw:
1) Sure, some may think it's more fun (can't imagine why, but to each his own, it's as fair an argument as any), but many don't. Believe me, as more and more people get the game, more and more people will complain about this.
2) For those who think it takes "no skill" if there were not such terrible law, I challege you to a game of Unreal Tournament. (And no, don't worry, Elite Dangerous would never become Unreal Tournament no matter what they did with the turn rates.) Saying it requires "no skill" is absurd, and just a way of getting people to shut up about it.
3) A LOT of people are going to be REALLY upset about this so it IS worth rehashing over and over. If you don't like it, ignore it.
I think to make everyone happy we should just make the turn rates depend on the ships. Some would have terrible yaw, some terrible pitch, some would be mediocre at both but good at neither. That seems to be a really happy middle ground AND add a lot to the game.
