To be honest new movements would be good for the game, I hope 343 will make major changes and not just keep it the same as halo 4, going back to the movements, prone would be excellent and very useful, climbing ladders is nothing major but it would be a nice addition, sliding would be amazing also, as for my wishes, I would like to have weapons customizations, by that I mean have diffrent colours for the gun and have cool skins, and also attachments, but I would not like it to be like cod instead make it unique
