well they tried the change way and clearly it failed only selling well because of it's name. Cod gets over 200k online always tho... If it anit broken don't fix it Halo was the game that was always different from every fps out to date thats why everyone Loved it so much. Now its basicaly the same dumbdown gameplay as the rest which completely turned off 9/10 of the people who purchased it. Cod class system is the same as halo's you get perks killstreaks and such. When i used to play halo all i and everyone in lobbies i played with said it felt like a more frustrating version of cod, The game needs a skill gap it needs to get rid of all the randomness this is not a cod game and break back the old school arena shooter. I beleive they wont do this tho considering 343 is running everything we will see it is very sad to see everyones favorite franchise die because it decided to mimic other games and stray from being its own game. I'd probably play halo 3 all day everyday if servers were fixed It is still a great game aside from the hackers and such.
