You never know with pirates nowadays. Hell , they may even go so far as to make a server that can act exactly like a ubisoft server , give a crack that edits the game to connect to the pirate's server and then make an account and play the game illegaly. But then , you'd still have the prob that if you're internet connection gets disabled or something , then your progress will be lost :D ( I'm not a pirate , I'm just expressing my opinion )
