I think it would be pretty cool to have armor effects in Halo 5. They should return the ones from Reach, and a few new ones. For example:
Promethium: When killed, a small slip-space portal opens which pulls the killed player in (just like the Warden)
Supercombine: Pink crystals and sparks can be seen on a Spartan’s armor
Requisition: On death, you hear a req pack opening (the one when you receive a legendary) sound and small req card particles pop out and float down, and eventually dissapear.
Abyss: Grey shards with a orange-red ish glow can be seen orbiting around the player. (By shards i mean the materials promethean weaponry is made of.)
Hologram: A hologram of yourself can be seen IN the player when standing still and slightly behind the player when walking.
Halo: a small Halo Ring can be seen floating above or around you. (To be honest, i’m not quite sure how that’s gonna work either.)
Stalker: A trail of plasma can be seen on the ground where a player has walked.
