Indeed. And why not have them in every gametype? Halo 3, Ever heard of that? The game that allowed you to play as a Sangheili whenever you wanted and not just when selected to.
Personally I think they should return that trait as it was fun to play as an Elite in Halo 3. Screw the little kids and their petty comments. Sangheili are born fighters, Spartans have to be enhanced and many don't make it.
PS: To the guy who wants to be a Skirmisher Kig Yar. I share that desire. *Is Skirmisher Fanboy*
