I agree. The Arbiter was found to be very useful, imho. He would crouch, go stealth and camo alike, and give surpressive fire when fighting brutes. Bungie really overhauled the AI aspect of the game. It's just too bad that the game wasn't long enough. I don't about you, but I can't enough of the story. Maybe this calls for a run-through on Legendary with all the skulls, expect Blind on? Hummm... Oh, yeah. I've been unactive here on the forums due to Halo 3 infecting my gray matter.
