I think that the way Bungie handled Spartan armors is probably the way they will handle females in Destiny. Miranda Keys was also always fully clothed, and not sexualized in any way. Of course, we will always have Cortana but that's a whole different ball of wax. More important than what female characters in Halo have worn, is how they acted. Every female has been of strong character, and mostly absent of any sexual stereotype whatsoever. If anything, I'd say Bungie goes out of their way to make this happen, and as a male gamer, I'd like to see a little bit MORE Mass Effect armor. But such armor is impractical, so I doubt Bungie will take such a route.
