Living Memorials have always been obnoxiously blue, and I think they just got bluer.

At the top of the screen are two actual blue mobs. At the bottom of the screen is a pack of white mobs. I like seeing blue mobs, and I don't like being disappointed when they're not actually blue mobs. This might not sound like a big deal but it's kind of a fundamental piece of the enjoyment of leveling.
