if you honestly think those four aspects you just mentioned turn the game from halo to COD......then maybe you should take another look at halo. Did they make you jump a centimeter off the ground? did they make you die in every firefight an instant? at it's core, this game is still halo.
Personally tI have gripes with 3 things, I'm not entirely confortable with is the personal ordinance, more because of the loss of power weapon spawns. I do believe it's a nice idea but it leads to way to many power weapons at one time. JIP should be taken out IMO, it just doesn't work plus I'm assuming it factors into my other gripe, the terrible player matching pre-games.....seriously starting in a lobby of 4 players then ending up in a 3 v 1 game is beyond stupid
