>>86637811/12 collector here.
I know your post is mostly bait, but remove the exaggeration and you have some good points.
>1/6 collectors are doll lovers who can't pose nor take pictures if their lives depended on itThis is mostly a problem of Hot Toys collectors, since the only HT figure that can actually pose is Alita. There are actually a huge range of great-looking, but expensive-as-fuck, 1/6 scale figures.
>1/18 are army builder GI Joe basement weirdosUnfortunately the crowd on here really help your argument. I would have a separate collection of 1/18 if I could afford it and had the space. I love the fact you can get heaps of cool mechs and vehicles and I love the post-apocalyptic vibe of JoyToy, Acid Rain World and Planet Green Valley.
But yeah, 1/12 has more of what I want for a decent size and I can get super-articulated figures that can actually hit decent poses. So there's that.
