If i remember from The Flood didn't Guilty Spark mention that Spartan-117 was wearing a class 2 suit or something to that effect and the standard for the forerunners fighting the flood was i THINK a class 12(whatever that means)So to that degree i dont think the body suit would cause it much delay or issues. NOTE: i do not currently have the book beside me so the class 2 and class 12 numbers are pulled from the air and my memory but i think it was stated by Sparks that it was six times more powerful then the Spartan suits.
