And that is what happened I believe. They were not listening to player feedback, because they 'wanted to finish the vision', and when they 'finished the vision' - it was too late. Of course no one can predict such things while they happen in real time, but the game should've been reverted back in 2008-2010, now it maybe too late. Like someone said previously in other thread, the ship has sailed.
Even if it was not the 'original vision' - by accident or chance or luck or lack of resources - they created gameplay which was something not done before or after. So actualy if they 'finished the vision' in 2005 - they broke the game that already thousands of people were playing and loved. So in essence 'the original vision' was worse than the 'half vision' that was already created.
