The only way you get people to improve is to officially allow parsers/fflogs and to make it so that you won't be punished if you call people out for poor performance in pf/df. SE will never do that because the majority of the sub paying players are super casual and would be turned off from the game, if SE were to go that direction. That means less revenue for the game and less resources to fund development of new raid content for players who like to push end game.
