Lightsteel Shield

I only recently discovered this shield model, having completely missed it somehow between MoP and now. I was surprised it was so old, going on the very sci-fi looking appearance I assumed it was BfA or SL, since both expansions got some sci-fi style gear.

I wish there were more variations of this with the markings and pulsating "power core" in different colors. I would love one with a purple core to match the purple markings (the gold/yellow variant has a purplish power core), and one with neon pink markings/core.
