Guild Wars 2: Engineer Elite Specialization Models Datamined

We know very little when it comes to the Warrior, Thief, Elementalist and Ranger specialization but thanks to That_Shaman over on Guild Wars 2's Reddit, we now at least know what the Engineer's drones look like and the fact they have names. They are:

Torch Shield Mine (the blades) Gun (the vents) Heal (the legs)

That_Shaman also states there's several icons on the tail for each: 

Bubbles Bomb Eyes (as shown in the screenshots) Blade Sparkles Shield Chains

As to what the drones do or how they'll function? We have no idea. I hope to god they aren't anything like the minions for Necromancer because they'll be a liability. Pet AI seemingly isn't ArenaNet's strong suit. There's a side of me that would like them to function similar to a Ranger's Shouts. You select a target, use the skill and the drone would appear and make its way to your foe before detonating. I think that'd be a fun solution to an AI problem.
