Opinions on MP

I just got my copy yesterday and I played a couple of matches, my impresions was that the mechanics of mantle and unlimited runing kills the feel of the clasical Halo. I think I like more the MP on the MCC than in this game. BTW I was pretty good in Reach but also I don’t like it the feel of the BR or DMR in this game, you die faster with the other have a AR at medium distance.
