Halo 4's only half decent CTF MM map is Complex, and I originally despised that map. Now why is that map the only working CTF map? Because you can push with Ghosts, as they function as power vehicles in that sandbox. CTF Adrift ,which I thought would be great, is unplayable. With no power weapons except for the sword of uselessness, its just teams camping their base until the other team quits pushing, retreating to their base to camp the enemies push. Rinse. Repeat. Since there is NOTHING to serve as an incentive to move, camping is extremely viable. Oh, and if they manage to capture the flag once, you might as well just quit, as they can just stay in Adrift's base, raining down DMR fire upon anything that moves.
