I just recently played the gametype today, and I have to agree that it is a very poor representation of classic Halo gameplay. The tweeks were nearly unnoticeable and miniscule, and the biggest changes were also the biggest problems. The grenade usage is ridiculous, and the large amount of grenade warnings I see on my screen at any given time is unreal. I personally don't think there is a way to execute this right. It is far too late in development, and all the maps have Halo 4 mechanics in every nook and cranny. The sightlines just don't work, and you are going to be fired on from all sides all the time. At first I thought this was a great idea, but now that it has been executed it seems that without MAJOR map editing this gametype is just "Team Die A Lot of Times and Use Grenades"
