I love metal minis. I'm sure it's because I grew up with them, and the look and feel and weight all seem more 'right' than with any other common material. I have grudgingly accepted plastic as the material used by GW. If metal isn't an option, plastic is certainly a better choice than resin, which was just always awful.
8th edition teaser article was about Necrons, I dug mine out. My son has a proper Necron army, but these guys are mine.
The whole cadre.
Necron Lord (whatever they're called now) and four Immortals.
We're going to keep calling these 'Destroyers', because close enough.
A couple of these bases are resin casts, but it's so hard to tell which, it doesn't matter.
