Doubt you will understand it but try reading it. Might explain alot to you but I doubt it. Your a alpha tester not that u probably know what that is and the game is under development not that u probably know what that is either and until its released they can if they want have the servers up 10 min a day if they want too or not at all. You probably should read what u pay for before u cry about what u paid for
