Is the warriors' dominance good for the nba or bad overall?

Most would say there's 2 great teams. If, according to you, the number is as high as 3-4, it's no different from previous years. Or are we going to pretend it was somehow better when the Lakers and Spurs won 9 of 12 championships between 1999 and 2010? We're witnessing the reign of a team that will, as the years go on, ever more be talked about as among the greatest of all time, a famous era in NBA history that we get to experience first hand. And this is bad?
