Okay. A beta is a little more than a demo. It is a testing phase to find balance and bugs. Look at Halo Reach. The beta had cloaking very balanced. Complete invisibility, scrambled radars, deafened you, short length and long recharge speed. Now in the full game you move too fast and you become visible, you can hear things around you and it lasts for a while. Big mistake on Bungie's part as the skill has become almost useless. Point of the matter is changes can still be made but people gotta stop crying so much. They will do whatever they wanna do.
