It means they arent useles and getting them is fun now. A dev said that a sword with speed on it will now give you about 6% movement speed over the 1.5% it did before. So if you get 3 items with speed you now run at 118% stacking with other class niches of course. A paladin with Pursuit of justice would have a baseline speed of 133% with 3 speed items.
