The problem doesn’t lay with AL itself, the true problem is that the rest of the AAs are alot less useful in comparisson to AL.
Sprint: Increase its duration, simple. Given the fact Spartans are trained their whole lives and are genetically and physically modified don’t you think that they can sprint for longer than 5 seconds.
Evade: Increase the amount of evades per circle to 3. Take a page from Gears of War’s book.
Active Camo: Not much needs to be changed on this one, but, remove the whole it fades when you move thing and reduce the radar jammer by a few metres, the sound deafening is fine.
Jetpack: Fine as it is, just reduce the noise it makes a iddy biddy bit.
Hologram: Make the Hologram itself appear red on enemy radar and have enemy reticules turn red when they target holograms and have your tag appear above it, same as it would on your character.
Drop Shield: Make it a little more durable, because lets be honest it doesn’t last very long, (and bring back ball of doom)
Armour Lock: Fine as it is, perfect counter to vehicle whores and grenade spammers.
