Make a tweak to all armor abilities if necessary

Sprint - Make it last a little longer
Evade - Fine as it is
Hologram - maybe make it so the tag will appear above it when used
Jetpack - longer recharge time
Armor Lock - Make it able to shed stickies again; it’s so useless since it can’t shed stickies
Active Camo - Make it like Arbiter’s in Halo 2 (It lasts 7 seconds with a recharge time of 13 seconds, but you’re fully cloaked during the whole duration) This would make it short and sweet and solve the camping problem… and get rid of that useless Jammer.
Drop Shield - Fine
