I don't know why they removed them in the first place, this also restricts machinimas as well. I can't repeat myself enough, but removing playable elites was a bad idea, but it's still a good game.
I would like an assassination where you kick them in the back of the leg, and grab there head while stabbing them in the chest as they collapse to their knees.
I hope that this thread may give 343i the intensive that playable Elites are a necessity in halo multiplayer AND machinima purposes since there are So many restrictions in that sense. Not to mention they're just fun characters to play as. So I again I hope they go through with it, because It would make Halo 4 all the more useful and enjoyable.
