Interesting ideas about the armor abilities but if they are "pick ups" we will end up with people camping on there spawns so i think keep the AA's how they are it works and sprinting adds a level of desperation to the game i think, "I have to get there to help" or "get me the hell out of here" sorta feelings come out when using sprint and if a map can be dominated by an AA, you have it as well so whats the problem really
