All you casuals complaining about Jackals. You never did the Jackal Two-Step. One shot in the small gap on the side of the shield, and one in the head. Jackals were almost as easy as grunts. The snipers even more so, they didn't even have shields. Hunters were easy to dance around. Brutes had no shields, and so headshots were way easier than Elites. Drones you could headshot easily as well. All in all, Elites are the hardest Covenant enemies in the Bungie Halos bcuz shielding (Read Halo: Reach Legendary Elites). None of the Flood were particularly difficult except those needle launching/Tank morphers. Not a big fan of them but they weren't difficult. Watchers would tick me off in Halo 4 because they would always run away and no headshots. But the Promethean Snipers would've been worse if their AI weren't so stupid and predictable.
