I do miss the competitive-ness of Halo 3, but I do enjoy the updated graphics and the story of 4. As for the "armor abilities", i equip them; then promptly forget that I have them. We all know how armor lock worked out in Reach. Use, wait, throw, die... The sprint I don't mind, means I can get back to the front faster. Please for god sake, return the kill based matches, this point stuff sucks.
