Here's an idea from an asshole: Why not have an enemy that spawns disguised as a random item (AP Ammo, Barrett, C4, etc) that cannot be distinguished from the real deal (including being invincible) until interacted with? When the player goes to pick up the Mimic, it becomes vulnerable (low health; easy kill) and its only ability is to hug the player (see where I'm going with this?) at a super short range. It can't ninja hug you out of nowhere; you'd have to be on top of it. As long as you're with another player, they pose very little threat. However, if you're off item whoring (and aren't a cloaked mobility recon or his flying purple item eater) you can kiss your HMG stealing ass goodbye. Adds an element of surprise, makes it harder to be an item whoring dick, and is going to provide many laughs for all to share.
