There is no question on this addition(Go to general discussion and look at the 400+ page thread on the subject). There has to be sangheili characters playable in halo 5 multiplayer(Although make them the intimidating Elites of Reach not the -Yoink- of 4). Of all the things that people ask for in halo 5, the movement to bring the Sangheili back as a playable character is the largest which is reason enough for it to be considered.
