The campaign brought new elements to the table which was kind of cool. I liked ODST and its somber feel, and transition from MC. So yes to an extent I like Reach campaign. However I do agree that the characters were hard to connect with. Kat was lame, Emile was a punk. Carter was stereotypical. Jorge and Jun were the only cool ones.
I only use sprint, armor lock is only good against vehicles. jet Pack is worthless if you know how to play the game. Hologram is lame (glad it is being updated for Halo 4), and active camo was not active camo.
The mechanics of Reach are busted and the weapons do not function as they should. A headshot should be a headshot, a stick with a sticky should be a stick etc.
Reach was ok...Halo 2/3 were way better
