Armor Lock vs. Top Speed, Approaching Ghost = Super Awesome!
Don't forget that in Halo 2 the Covenant deployed a massive Bug called "Scarab", which could only be destroyed by boarding it and killing everything aboard, and later on (Halo 3) they downgraded it so that now you could destroy it even without boarding it. Same for Phantoms, first you had Spirits, which were completely indestructible, then (Halo 2) you have the new Phantoms, which can't be destroyed, but the weapons can. Then (Halo 3) the whole design was downgraded! Now you CAN kill Phantoms! Let's not forget of course, about the completely useless camouflage! First you had a 100% working one, then a silhouette could be seen, later on you were completely invisible, only when standing still, if you moved an inch, you could be completely seen. It's like the Covenant and the Humans agreed to make things worse for both sides! xD
