like above said about hologram, i think hologram would be great if it was real enough do deceive your enemies. As for armor abilities in general i think there great especially for beating someone with a power weapon or vehicle
(ex rocket launcher and armor lock, or stealing a banshee with jet pack), and i also think sprint and evade shouldnt be a ARMOR ABILITY but something everyone has by default, its called ARMOR ability, its supposed to be an add on to ur armor
