Well, many people are claiming about Armor Abilities; and I think AA annoying sometimes too. But I don't think fair to get rid of it but changing or upgrading it.
- AA should be replaced by PE (Personnel Equipments). It pretends to work like an individual "weapon", almost like "buffs" in Halo 3 (invisibility, overshield, etc.). but like solid equipments to wear instead "magic balls". So the PE can be found around the map, preferably at some armory house. So the equipments to wear should be a jetpack, promethean eyeglass, fuel for thruster, chip to engage invisibility, etc.
- Also it would have BS (Battle Support). It pretends to be similar or equal to the bubble shield, health regenerate and power swallow (I'm sorry, I don't now how it named). Well, it should be some thing like a "special grenades", when it's thrown it make whose effect. Well, it's only to get back what was at Halo 3.
