I thought the Explosive Bolts of the Dropships made them more fearsome; in past games I saw a Phantom and thought "Oh wow, more troops." Now I see one and think "Oh crap, more troops and a mean-ass gun."

Why did they remove the Covenant Carbine? That weapon was so great in Halo 3. I wish they would've added it to all maps and would have kept it in the series.
